	Use '<span id>' instead of '<a name>'.
	(_convert_printindex_command, _convert_def_line_type):

	The 'name' attribute of <a> to define a hyperlink target is 
	deprecated in the HTML 5 standards.  'id' for this purpose was 
	specified by HTML 4 (in 1997) and can be expected to be 
	supported by all browsers.

	* tp/Texinfo/Convert/HTML.pm (_file_header_information): For 
	split output, if SECTION_NAME_IN_TITLE is set, try to use the 
	argument of the chapter structuring command instead of @node for 
	the contents of <title>.  Feature suggestion from Akim Demaille
	(help-texinfo, Nov. 2018).

2019-01-01  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix error message from texinfo-js.

	* js/texinfo-js.in: Remove extra `-' from an error message.  
	Report from Stefan Husmann.

	Document 'TEXINFO_XS_PARSER'.

	* NEWS: Mention the XS parser implementation.
	* tp/Texinfo/Parser.pm: Note that this module can be overridden.
	* doc/texinfo.texi (texi2any Environment Variables):
	Add TEXINFO_XS_PARSER.

2018-12-29  Gavin Smith  <gavinsmith0123@gmail.com>

	Pass on -D to texi2dvi.

	* tp/texi2any.pl: If calling texi2dvi, pass along the values of 
	any flags set with -D on the command line.  Suggestion from 
	Olivier Dion.

2018-12-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove implementation of @cropmarks in texi2any.

	* tp/Texinfo/Common.pm (%line_commands): Remove 'cropmarks'.

2018-12-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove documentation of @cropmarks command.

	* doc/texinfo.texi (Cropmarks and Magnification, Magnification):
	Rename and remove mention of @cropmarks.

2018-12-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove @cropmarks command.

	* doc/texinfo.tex (\cropmarks, \ifcropmarks, \onepageout): 
	Remove implementation of @cropmarks.
	* NEWS: Mention @cropmarks removal.

	This command has hardly ever been used and it is questionable 
	whether it has worked correctly for many years.  See bug-texinfo 
	discussion November 2018.
	The code was introduced in 1986 by Pierre MacKay for use by 
	"Near East Publications".

2018-12-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Tidy up info test suite infrastructure.

	* info/t/Init-test.inc: Do not set GINFO_NAME variable as it is 
	not used.  Do not set infodir variable.  Do not try to set 
	srcdir, as it is already set.  Change some shell variables to be 
	lower-case, to avoid confusion with variables exported to the 
	environment.  Remove unused variable GINFO_OPTIONS.

2018-12-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Select correct cross-reference.

	* info/session.c (info_menu_or_ref_item): If there is more than 
	one cross-reference in the line after the point and no 
	cross-reference contains the point, use the first 
	cross-reference after the point, not the last one in the line.  
	This means that the cross-reference that is highlighted as 
	"active" will be the one that is used.

2018-12-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Avoid memory leak for malformed files.

	* info/nodes.c (info_load_file): Free 'contents' and 'encoding' 
	fields of file structure in case the node table couldn't be 
	built.

2018-12-28  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix call to info_find_file.

	* info/nodes.c (info_get_nodes_with_defaults): Restore the value 
	of the 'fullpath' field of a file structure before calling 
	info_find_file.  Otherwise, info_find_file will not recognize 
	that a file has been loaded, and load it again.  This can lead 
	to a file buffer being freed incorrectly in 
	gc_file_buffers_and_nodes, leading to a segmentation fault.  
	Segmentation fault reported by Keith Thompson.

2018-12-01  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Makefile.am (Makefile.docstr): Fix to work out-of-source.

2018-12-01  Gavin Smith  <gavinsmith0123@gmail.com>

	Fix info/t/all-only.sh test in out-of-source builds.

	* info/dir.c (dir_entry_of_infodir): Prefix a non-absolute path 
	with "./" so that other parts of the code recognize it is the 
	full path.

2018-12-01  Gavin Smith  <gavinsmith0123@gmail.com>

	* NEWS: Development now uses git.

2018-10-29  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi) <inline conditionals>:
	Avoid an infinite loop when skipping an unexpanded conditional
	in case we run out of input.
	* tp/t/55conditionals.t (inlineifset_false_not_closed): New test.

2018-10-29  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi) <@inlinefmtifelse>:
	Avoid an infinite loop if there is no more input.
	* tp/t/55conditionals.t
	(inlineiffmtifelse_not_closed, inlineiffmtifelse_not_closed_two_arg)
	(inlineiffmtifelse_not_closed_three_arg): New tests.

2018-10-28  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_check_line_directive): Fix code for
	checking if input is coming from a file.

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_next_text, _new_line): Do not pass
	$current as an argument, as it is not used any more now the
	check for the #line directive has been moved out.

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/80include.t (cpp_lines): Add test of macro where a
	line that looks like a #line directive is not the very first
	line, as these may be treated differently by Parser.pm.

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_check_line_directive, _save_line_directive)
	(_next_text): Split out sub from _next_text.
	(_parse_texi) <BEGIN LINE>: Call _check_line_directive and
	_save_line_directive.  The condition for #line being meaningful 
	is the same as what was in _next_text.  

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (#line directive) <CPP_LINE_DIRECTIVES>:
	Add a missing ).

	* tp/texi2any.pl (set_from_init_file, set_from_cmdline),
	* tp/Texinfo/Convert/Converter.pm (set_conf, force_conf):
	Do not call Texinfo::Common::obsolete_option.
	* NEWS: Mention that obsolete customization variables are no 
	longer recognized.

	* tp/Texinfo/Parser.pm (_setup_parser): Do not look at 
	'INLINE_INSERTCOPYING'.

	If more variables are deprecated, then it may be worth 
	reinstating some of this code.

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_command_with_command_as_argument):
	Remove code checking for a case where the command has two 
	elements in 'args', the first all whitespace, as this case never 
	seems to happen.

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (@titlefont @center @sp):
	Do not mention the possibility of using these outside of a title 
	page.

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%in_index_commands): New hash, 
	containing only 'sortas'.
	* tp/Texinfo/Parser.pm (%in_full_text_commands): Do not 
	specially remove 'sortas'.
	(_setup_parser, _parse_command_line_args): Use 
	%in_simple_text_commands for the commands that may appear in 
	index commands.  This was done until 2017-04-01.
	(_parse_texi) <brace commands>: Move check for valid nesting of 
	@sortas here.  Change error message to mention index entry.

2018-10-27  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi) <in heading commands>:
	Do not set an 'invalid_nesting' value.

2018-10-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_check_valid_nesting): New sub, split 
	out from _parse_texi.
	(_parser_texi): Call it.
	(%in_full_line_commands): Remove useless variable, as the same
	as %in_full_text_commands.

2018-10-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (%in_full_text_commands): Do not
	allow @indent, @noindent.
	(%in_full_line_commands): No exception for @indent, @noindent.
	* NEWS: Mention change in allowed nesting.

2018-10-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (%simple_text_commands): Add all the 
	commands that have a number >= 1 as their argument type in
	%brace_commands, except for inline conditional commands.  This 
	includes @inforef which wasn't included before.  This leaves 
	only @shortcaption and @math as explicitly listed commands.

2018-10-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (%no_command_commands): Remove this list 
	of commands that shouldn't contain any other commands.  Although 
	it is valid, it makes the picture of which commands can contain 
	others more complicated for the sake of only a few commands.
	Introduced on 2016-07-09 for @errormsg and @U.

2018-10-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%brace_commands): Change meaning of 1
	as a value.  Now only commands that were in
	%simple_text_commands in Parser.pm have 1.  Use words as well as 
	numbers, as is done for %line_commands.  Accent commands get 
	'accent'.  Style commands get 'style'.  Context brace commands
	get 'context'.  Various other brace commands get 'other'.
	(_parse_line_command_args): Commands defined by @definfoenclose
	get 'style'.

	* tp/Texinfo/Parser.pm
	(%simple_text_commands): Change initialising code to use 
	%brace_commands for some brace commands. This shortens a 
	seemingly arbitrary list.

	(%full_text_commands): Update initialising code for new meaning 
	of %brace_commands.

	(_parse_texi): Change two conditions to compare values of 
	%brace_commands hash, without needing to look at 
	%simple_text_commands.  Remove an unnecessary conditional.

	* tp/Texinfo/Parser.pm (_parse_texi),
	* tp/Texinfo/Convert/Plaintext.pm (%brace_no_arg_commands):
	Use "eq '0'" instead of "== 0" for %brace_commands values.

	No functional changes intended.  This brings the implementation
	closer to the C version under tp/Texinfo/XS/parsetexi.

2018-10-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (%simple_text_commands): Add 'sortas'.
	(%full_text_commands): No special case for 'sortas'.
	(_parse_texi) <@copying in @insertcopying>: Undefine a variable.

2018-10-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_isolate_last_space): Set 
	'comment_at_end' value on element instead of parent.  As well as 
	gaining consistency with 'spaces_after_argument', this means 
	that a comment at the end of a brace command argument is not 
	lost or output at the wrong place.  Add a comment noting that 
	comments should not be inside brace commands anyway.

	* tp/Texinfo/Convert/TexinfoXML.pm (_convert_argument_and_end_line),
	* tp/Texinfo/Convert/Texinfo.pm (convert, _expand_cmd_args_to_texi):
	* tp/Texinfo/Convert/Converter.pm _expand_cmd_args_to_texi): 
	Access 'comment_at_end' in the new place.

2018-10-23  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm: Change 'same than' to 'same as' in
	comments.

2018-10-23  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (%simple_text_commands): Remove @ctrl.

	* tp/Texinfo/Parser.pm
	(%begin_line_commands, %in_full_text_commands):
	Initialising code changed.

	* tp/Texinfo/Convert/Common.pm (@inline_types): Remove 
	'misc_command_arg', as no such element type is used anywhere.

	The reason for this change is that "line command" is more 
	descriptive than "miscellaneous command".  No functional changes 
	intended.

2018-10-22  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi):

2018-10-21  Gavin Smith  <gavinsmith0123@gmail.com>

	(Karl, bug-texinfo 2012-04-01).

2018-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%line_commands): Change a comment.
	(%other_commands): Set from %in_heading_commands.

2018-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%other_commands): Remove 'itemx'.  
	@itemx is always a line command.
	* tp/Texinfo/Parser.pm (_parse_texi) <misc commands>:
	Only @item can sometimes be an 'other' command', not @itemx.  
	Error message for incorrectly nested @item or @itemx.
	(_end_line): Add a check for an undefined value.

2018-10-20  Gavin Smith  <gavinsmith0123@gmail.com>


	* tp/Texinfo/Common.pm (%line_commands): Add all the sectioning,

	rather than 'misc_commands'.

2018-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi) <misc commands>:
	Deal with the commands that do not take a whole line as an 
	argument separately from those that do, using %other_commands 
	hash from Common.pm.  Reinstate error message for @insertcopying 
	inside @copying.

2018-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_item_line_parent): If current element 
	is an @item or @itemx, do not check the parent of the parent of 
	the current element.  This leads to a false positive for a 
	@table nested within an @enumerate.  It is possible that this 
	was intended to account for the parent element being a 
	'table_term' element, but the condition is not met in the entire
	test suite.  (The false positive was not hit in practice due to 
	_item_container_parent being called before _item_line_parent.)

2018-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%line_commands, %deprecated_commands):

	hashes.

2018-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%misc_commands):
	Change @insertcopying argument type from 'noarg' to 'skipline'.

2018-10-20  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_end_line) <@multitable>: Give a warning 
	messaage for any @-command appearing on the multitable line 
	outside of a braced prototype.

2018-10-19  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/tests/sectioning/list-of-tests: Do not run every test
	twice, once with '--html', once with '-c TEXI2HTML'.  Only use 
	the latter.

2018-10-19  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/tests/run_parser_all.sh: Do not substitute a
	"@PATH_SEPARATOR@" sequence in the list-of-tests files.
	It is only used in one test so is not worth the complication.
	* tp/tests/sectioning/list-of-tests (test_two_include):
	Remove this test.
	
	* tp/defs.in: Do not set PATH_SEPARATOR.

2018-10-19  Gavin Smith  <gavinsmith0123@gmail.com>

	Remove.  Similar tests exist under tp/t/30sectioning.t.

2018-10-19  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/defs.in: Do not set srcdir if it is already set.

	"make distcheck" works again now.

2018-10-19  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/tests/sectioning/list-of-tests (test_two_include): Move an 
	input file to this directory.

2018-10-19  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/test_utils.pl: Create the output directory for the test
	before running the conversion.  This means that if the test 
	needs to create output files, the directory to contain them will 
	exist.  It didn't exist the first time a test file was run when 
	the very first test in the file needed to create output.
	If there are conversion errors from texi2any, print them instead 
	of just printing a message "Warning: output generated".

	Remove.
	* tp/t/92formatting.t: Add the same tests.

	(simple_with_menu_docbook_info): Remove.  This tested the 
	combination of "--docbook --info" which is equivalent to just 
	"--info".

2018-10-18  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/tests/run_parser_all.sh: Source 'defs' before setting

2018-10-18  Gavin Smith  <gavinsmith0123@gmail.com>

	* README: State that we may use a range like 2008-2010 in

	such a statement.)

2018-10-18  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_line_command_args) <@definfoenclose>:
	Add new command to %brace_commands.  This avoids having to check

	places.

2018-10-17  Gavin Smith  <gavinsmith0123@gmail.com>

2018-10-13  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Makefile.am: List files under tp/t/include_reference.

	Remove copyright notice from generated file as the year is 
	out-of-date.

2018-10-13  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/test_utils.pl: Remove code copying 't/include_reference'
	to build directory.  Do not include any directories in the 
	current directory in the include path.
	* tp/Makefile.am (all-local): Do not depend upon these copied files.

2018-10-13  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/test_utils.pl, tp/t/nodenormalisation.t:
	Put tp/t/include_reference in srcdir in include path.

	* tp/t/80include.t (test_paths, test_include_directories): 
	Remove tests.
	* tp/t/converters_tests.t (verbatiminclude_paths):
	test_include_directories): Remove tests.
	* tp/t/info_tests.t (image_file_search): Remove test.
	test_include_directories): Remove tests.

	* tp/maintain/regenerate_file_lists.pl: Do not generate rules to 
	copy files to tp/t/include_dir in build directory.

	This avoids the hassle of copying all the include files to the 
	build directory for out-of-source builds and avoids the 
	confusion of which of "t/include", "t/include_dir" or 
	"t/include_reference" a test file is to be added to.  This 
	feature of the test suite is not used enough IMHO to be worth 
	the complexity.

2018-10-06  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_end_line) <@columnfractions>: Set the 
	'columnfractions' extra value to the element for the 
	@columnfractions command, rather than to the 'misc_args' array 
	of that element.  This is to make a 'misc_args' array only 
	referenced by one element, which makes it possible to free the 
	memory properly in the C rewrite.

2018-09-22  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/tests/formatting/list-of-tests (texi_glossary):
	Define test using '-c TEXINFO_OUTPUT_FORMAT=plaintexinfo'.  This

	Rename test and use '-c TEXINFO_OUTPUT_FORMAT=plaintexinfo' to

	".txi" extension instead of "texi", and in the out_parser_info
	directory, the output format will be info instead of texi.

2018-09-22  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/texi2any.pl: Allow '-c TEXINFO_OUTPUT_FORMAT' to override 
	'-c TEXI2HTML'.

2018-09-22  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi):
	Do not set a 'spaces_after_command_elt' value.
	(_abort_empty_line): Do not clear a 'spaces_before_argument_elt' 
	value.
	* tp/Texinfo/XS/misc.c (xs_abort_empty_line): Make the same change.

	(module documentation section): Remove mention of

	extra value.

	This is intended to simplify the parse tree.  Reducing 
	duplication of information makes it easier to track what data 
	leads to output at later stages of processing.  It reduces 
	memory use and may increase speed.  It makes it easier to 
	inspect data structures that are "dumped" to a text stream.  It 
	is also easier to handle memory allocation in a rewrite in 
	another programming language if the data structures are less 
	cyclic.

	* tp/Texinfo/Parser.pm (_abort_empty_line): Always get the

	* tp/maintain/regenerate_cmd_tests.sh: Do not print diffs if

	(definition_category): Refer to 'def_parsed_hash' instead
	of 'def_args'.

2018-08-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_def): Copy the element label in
	a 'def_args' pair into the 'def_role' extra value on the 
	element.

2018-08-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_def): Collect adjacent 
	non-whitespace elements into a 'def_aggregate' element and
	make this change in the main tree as well as in the 'def_args'
	array.

2018-08-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_def): Use the same hashes in the
	main tree as in the def_args array for the arguments on a
	@def* line.  This means that delimiter characters are in their 
	own elements now.

2018-08-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_def): Change the type
	of final spaces elements to 'spaces_at_end'.  This leads to
	the spaces being ignored in some output formats.
	(_next_bracketed_or_word): Remove unused.
	* tp/Texinfo/Convert/TexinfoXML.pm (_convert) <def commands>:
	Strip off a final newline.

2018-08-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_split_delimiters): New function.
	(_parse_def): Do not produce def_args array via an intermediate
	array of a similar format.  Use "map" with _split_delimiters to
	place [](), in separate elements, before processing the 
	arguments on the line.

2018-08-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_def): Reorder some code.

2018-08-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_split_def_args): New function.
	(_parse_def): Use "map" with _split_def_args to create the
	array of def line contents.  This does all at once what
	_next_bracketed_or_word did across all the times it was called.
	(_next_bracketed_or_word): Collect elements from the array that
	has already been processed.

2018-08-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Structuring.pm (new_block_command)
	* tp/Texinfo/Parser.pm (_parse_texi, _end_line):
	Do not set 'command' extra value on 'empty_line_after_command'
	or 'empty_spaces_after_command'.

2018-08-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Convert/TexinfoXML.pm (_convert): Remove 
	conditional block that checks for a raw formatting command (e.g.
	@html if --html is given to texi2any) that is being expanded.  
	It appears that this code is never executed as an earlier clause
	of the "if" statement is executed if this format is being expanded.

2018-08-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi) <CLOSED raw>: Do
	not add a 'command' extra value on the 'empty_line_after_command'.

2018-08-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_end_line) <after @end verbatim>:
	Do not use 'command' extra value to check if we are after
	@end verbatim.

2018-08-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/texi2any.pl: Set top_srcdir as well as top_builddir in case
	these are not defined.  This compensates for a recent change in
	Texinfo::ModulePath.

2018-08-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm
	(parse_def): Split up text elements in the main tree into 
	separate elements.  This means in most cases, the elements in 
	the 'def_args' hash and the elements in the main tree will be 
	the same.  (The exceptions are when "(" or ")" is split into a 
	"delimiter" element in def_args, and when there is trailing 
	whitespace on a line before the LF.)
	(next_bracketed_or_word): Include any trailing newline in the 
	returned values.
	(parse_def): Avoid adding elements with a trailing newline to 
	'def_args'.

	This change should only affect the main tree, not the value of 
	the 'def_args' hash, or the output from any of the converters.
	It is intended to reduce duplication of information in the parse 
	tree, and to make handling of allocated memory simpler in the C 
	replacement for this module.

2018-08-23  Gavin Smith  <gavinsmith0123@gmail.com>

	* util/htmlxref.cnf: Remove gcj, info.  Add cvs.  Report from 
	Ineiev <ineiev@gnu.org> and Thérèse Godefroy <godef.th@free.fr>.

2018-08-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/xspara.c (xs_unicode_text, xs_process_text):
	Use static buffers to avoid memory leaks.

2018-08-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/xspara.c (xspara_get_pending, xspara_add_pending_word)
	xspara_end, xspara_add_next, xspara_add_text): Save storage for 
	text buffers in static variables to avoid memory leak.
	* tp/Texinfo/XS/text.c (text_reset): New function.

2018-08-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/misc.c (xs_parse_texi_regex): Retain all memory
	allocated on the heap in static pointers.  Perl does not free 
	them, as when SV's are initialized with sv_setpv, the data 
	pointed to is copied, not the pointer itself.  This memory leak 
	is visible with valgrind, e.g. run TEXINFO_XS=debug PERL_DESTRUCT_LEVEL=2 valgrind --log-file=val.log --leak-check=full perl -w t/02coverage.t commands

2018-08-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Makefile.am (EXTRA_DIST) Do not distribute tp/Makefile.PL 
	or tp/MANIFEST.
	* tp/Texinfo/XS/Makefile.am: Do not distribute Makefile.PL,
	MANIFEST or prepare_standalone_perl_module.sh.

	This is to reduce confusion about whether these files are needed 
	for "make dist".

2018-08-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/README: Clarify purpose of regenerate_file_lists.pl.  Do 
	not mention prepare_perl_module_files.sh.

2018-08-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS: Run "gnulib --add-import strndup".

2018-08-15  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS: Put subdirectories 'lib' and 'm4' inside new 
	subdirectory 'gnulib' (as is done in the top-level gnulib 
	import).
	* tp/Texinfo/XS/Makefile.am (AM_CPPFLAGS, ACLOCAL_AMFLAGS, SUBDIRS)
	(EXTRA_DIST),
	* tp/Texinfo/XS/configure.ac (AC_CONFIG_MACRO_DIR, AC_CONFIG_FILES):
	Update.

2018-08-15  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/configure.ac (AC_CONFIG_FILES):
	Add parsetexi/Makefile.
	* tp/Texinfo/XS/Makefile.am (SUBDIRS): Add parsetexi.

2018-08-15  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/ModulePath.pm.in: Add 'parsetexi' directory to 
	@INC.
	<TEXINFO_XS_PARSER environment variable set>: Add a subroutine 
	to @INC to override Texinfo::Parser with Parsetexi.pm.

2018-08-15  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/texi2any.pl <finding version number>: Refer to 
	Texinfo::Common instead of Texinfo::Parser.

2018-08-15  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/texi2any.pl: Do not check for module files relative to the
	installed location.

2018-08-15  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/ModulePath.pm.in: Do not account for the case of 
	one of $top_builddir and $top_srcdir being set but not the 
	other.

2018-08-15  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/Makefile.am: Do not install TestXS.pm, as this 
	is useless.

2018-08-15  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/texi2any.pl: Only call fileparse once (used for both 
	finding modules and translation files).  Do not add a directory 
	to @INC that Texinfo::ModulePath takes care of adding.  Add a 
	comment.

2018-08-14  Gavin Smith  <gavinsmith0123@gmail.com>

	* autogen.sh: Initialise tp/Texinfo/XS directory.

2018-08-14  Gavin Smith  <gavinsmith0123@gmail.com>

	* configure.ac (xs_srcdir): Update path from XS builddir to 
	srcdir.
	* tp/Texinfo/XS/fail.pl: update path to TestXS module.

2018-08-14  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/XS/Makefile.am (modulesdir): Change to new 
	location.
	(CLEANFILES, EXTRA_DIST, xs_LTLIBRARIES): Add MiscXS files.
	(MiscXS_la_CFLAGS): Define.

	* tp/Texinfo/MiscXS/MiscXS.pm,
	* tp/Texinfo/MiscXS/miscxs.h,
	* tp/Texinfo/MiscXS/misc.c: Move to tp/Texinfo/XS.
	* tp/Texinfo/MiscXS: Remove subdirectory.

	* tp/Texinfo/ModulePath.pm.in: Refer to Texinfo/XS instead of 
	Texinfo/MiscXS.

	* tp/Makefile.am (SUBDIRS, DIST_SUBDIRS): Remove Texinfo/MiscXS.
	* configure.ac: Do not configure in tp/Texinfo/MiscXS.

2018-08-14  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Convert/XSParagraph, tp/Texinfo/XS:
	Move subdirectory. This is intended to be a subdirectory for all 
	XS modules and to remove the duplication that exists between
	tp/Texinfo/Convert/XSParagraph and tp/Texinfo/MiscXS.

	* configure.ac,
	* tp/Makefile.am,
	* tp/Texinfo/Convert/Paragraph.pm,
	* tp/Texinfo/ModulePath.pm.in,
	* tp/Texinfo/XS/XSParagraph.xs,
	* tp/Texinfo/XS/TestXS.pm:
	Refer to Texinfo/XS subdirectory instead of 
	Texinfo/Convert/XSParagraph and namespaces beginning 
	"Texinfo::XS" instead of "Texinfo::Convert::XSParagraph".

2018-08-14  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/t/Init-test.inc: Do not check whether the terminal needs 
	to be reset with stty, because the command that caused this 
	problem ("read -t") is not being used any more.

2018-08-14  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/01use.t: Inline file tp/t/manual_tree.pl.

2018-08-13  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/ModulePath.pm.in (init): Remove subroutine 
	prototype.
	* tp/Texinfo/ModulePath.pm.in (import): Wrap 'init' to allow 
	using module with "use Texinfo::ModulePath".

2018-08-13  Gavin Smith  <gavinsmith0123@gmail.com>

	tp/t/test_protect_hashchar_at_line_beginning.t, tp/t/test_sort.t,
	tp/t/test_tree_copy.t, tp/t/xml_tests.t:
	Add "use lib '.'" to add current working directory to @INC, the 
	Perl module include path.  This directory is not present in @INC 
	in recent versions of Perl, which makes running tests from the 
	command-line (like "perl -w t/02coverage.t") difficult.  Require 
	Texinfo::ModulePath to add all the other required directories to 
	@INC.  As tp/Texinfo/ModulePath.pm is generated in the builddir, 
	this should work for out-of-source builds.

2018-08-13  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/01use.t: Use Texinfo::ModulePath.

2018-08-12  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (parser): Remove code allowing calling 
	this function in an object-oriented way.

2018-08-12  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (parser, duplicate_parser): Move code out 
	for duplicating an existing parser to a new function.
	* tp/Texinfo/Convert/HTML.pm (output) <renamed nodes>: Call 
	'duplicate_parser'.

2018-08-12  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%default_parser_state_configuration):
	Remove 'gettext' and 'pgettext'.
	* tp/texi2any.pl ($parser_default_options): Remove 'gettext' and 
	'pgettext'.
	* tp/Texinfo/Parser.pm (%parser_default_configration_subs):
	(%parser_default_configration_no_subs): Remove.  There are no
	subroutines in the parser configuration any more.
	(_setup_parser_default_configuration): Remove.
	(parser, simple_parser): Call dclone directly instead of 
	_setup_parser_default_configuration.  Do not check for CODE 
	values on the parser hash object when duplicating a parser.
	(_setup_conf): Do not check for CODE values on the parser hash 
	object when copying a parser configuration.
	(MODULE DOCUMENTATION SECTION): Remove mention of 'gettext' 
	configuration.
	* tp/Texinfo/Common.pm (warn_unknown_language, warn_unknown_split):
	Do not take a 'gettext' argument.  Callers updated.
	* tp/Texinfo/Report.pm (new): Do not set 'gettext' or 'pgettext' 
	on object.
	* tp/Texinfo/Convert/Converter.pm (converter): Do not set 
	'gettext' or 'pgettext' on object.

2018-08-12  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (__, __p): Copy functions from 
	texi2any.pl.  Place these in @EXPORT.
	(%default_parser_state_configuration): Refer to __ and __p
	for 'gettext' and 'pgettext' instead of stub functions.
	* t/test_utils.pl: Call Locale::Messages::bindtextdomain for 
	'texinfo' domain as well as 'texinfo_document'.
	* tp/texi2any.pl (__, __p): Remove definitions.

	* tp/Texinfo/Report.pm (__, __p): Do not take a first argument 
	that is a parser object.  Do not look at 'gettext' and 
	'pgettext' configuration values: call the functions in 
	Locale::Messages directly.

	* tp/Texinfo/Common.pm,
	* tp/Texinfo/Structuring.pm,
	* tp/Texinfo/Parser.pm,
	* tp/Texinfo/Convert/Converter.pm,
	* tp/Texinfo/Convert/Docbook.pm,
	* tp/Texinfo/Convert/HTML.pm,

	* tp/Texinfo/Convert/Info.pm,
	* tp/Texinfo/Convert/Plaintext.pm,
	* tp/Texinfo/Convert/TexinfoXML.pm:
	Do not call __ or __p as methods on a parser object: use the
	functions exported from Common.pm instead.

	The only effect of this change should be in the test suite where 
	the default stub values for 'gettext' and 'pgettext' were used 
	for Texinfo.  This should have no user-visible effect.  The name 
	of the translation domain ("texinfo") is no longer set from the 
	name of the package in texi2any.pl, but this was already 
	hard-coded in Texinfo/Report.pm.

2018-08-10  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/test_utils.pl (test): Avoid method call syntax for 
	calling Texinfo::Parser::parser.

2018-08-10  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.texi (Customization Variables for @-Commands):
	Mention that these variables are not passed on to TeX.  Comment 
	out commands that only do anything for TeX.  Report from Karl.

2018-08-10  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Convert/HTML.pm (_parse_node_and_warn_external):
	Call 'parse_node_manual' from Texinfo::Common instead of 
	Texinfo::Parser.

2018-08-09  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Report.pm (gdt): Remove unused call to pgettext.

2018-08-09  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/t/60macro.t (line_after_recursive_call): New test.

2018-08-09  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Transformations.pm (_new_node): Call 
	'parse_node_manual' from Texinfo::Common instead of 
	Texinfo::Parser, and do not call Texinfo::Parser::register_label.

2018-08-09  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Common.pm (%default_parser_state_configuration):
	Do not allow customizing the root parser context.
	* tp/Texinfo/Parser.pm (parser, simple_parser, _parse_texi): 
	Hard-code '_root' as the root context.
	* tp/t/accents.t (test_accent_stack, test_enable_encoding):
	Do not set 'context' on created parser.  Allow for an extra 
	level of element nesting on the tree returned from the parser.

2018-08-09  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_register_label): Remove a useless 
	variable assignment.  Remove an unused argument.  Do not return 
	a value.

2018-08-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/t/Infokey-config: Use C-x for aborting in echo area in 
	test suite.
	* info/t/echo-area-no-completions.sh,
	* info/t/index-apropos.sh: Update.

2018-08-07  Vitezslav Crhonek <vcrhonek@redhat.com>  (tiny change)

	* info/info.c (get_initial_file) <man page fallback>: Avoid
	leaking memory.

2018-08-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/t/Init-test.inc (run_ginfo, timeout_test): Record process 
	ID of background process that does the timing out, and kill this 
	process if ginfo exited first.

2018-08-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/infomap.c (default_emacs_like_ea_keys)
	(default_vi_like_ea_keys): Remove ineffectual key bindings.
	Remove key bindings for sequences beginning with ESC, as these 
	have not worked since ESC was made an abort key.  Remove binding 
	for "C-x o" as it is not possible to escape the echo area any 
	more.  Remove bindings for SPC and ? which are self-inserting.

2018-08-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/t/Init-inter.inc: File removed.  All contents moved into
	Init-test.inc.

2018-08-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/t/Init-inter.inc (init_interactive_test): New function,
	containing commands that were at the top-level of this file.

2018-08-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/t/Init-inter.inc (run_ginfo): Run ginfo inside a subshell 
	with parentheses instead of using "sh -c".  This enables the use 
	of "$@" and avoids the need for an extra level of quoting when 
	calling run_ginfo.  Time out the process outside of the 
	subshell.

2018-08-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/t/echo-area-no-completions.sh: New test.

2018-08-07  Gavin Smith  <gavinsmith0123@gmail.com>

	* info/echo-area.c, info/session.c (pause_or_input):
	Move to session.c.  Do not pause if there is already buffered 
	input waiting.

2018-08-07  Vitezslav Crhonek <vcrhonek@redhat.com>  (tiny change)

	* info/echo-area.c (info_read_completing_internal): Avoid memory leak.

2018-07-13  Niko Tyni <ntyni@debian.org>  (tiny change)

	Perl 5.28 introduced thread-safe locales, where 'setlocale'
	only affects the locale of the current thread. External code
	like 'mbrtowc' isn't aware of this thread specific locale,
	so we need to explicitly modify the global one instead.
	
	Without this we could enter a busy loop in xspara__add_next
	(Texinfo::Convert::XSParagraph) for UTF-8 documents when mbrtowc
	returned -1.

	* tp/Texinfo/Convert/XSParagraph/xspara.c (xspara_init)
	[Perl version >= 5.28]: Call 'switch_to_global_locale' and 
	'sync_locale'.

2018-07-13  Niko Tyni <ntyni@debian.org>  (tiny change)

	* tp/Texinfo/Parser.pm (_parse_special_misc_command) <@clickstyle>:
	Escape braces in regex to be compatible with recent Perl 
	versions.

2018-06-04  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Transformations.pm (_reference_to_arg):
	Refer to 'args' array instead of 'brace_command_contents'.
	(Makes a couple of tests failing since 2017-10-29 pass.)

2018-06-04  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Convert/Plaintext.pm (_convert):
	When checking if a node name in a cross-reference includes a
	`.', do not include in the check any manual name that may have 
	already been stored inside the paragraph formatter.  Rical Jasan 
	reported that an error message mentioning the "node name" would 
	be given for output like "(gcc.info)Debugging Options" which is

	Options".  (bug-texinfo 2018-02-09)

	* info/nodes.c (info_node_of_tag_ext): Always call 
	node_set_body_start regardless of the value of 
	preprocess_nodes_p.  Benno Schulenberg reported that searching 
	commands could find matches in the node information line if the 
	use set "hide-note-references=On".

	\sevensl, \sevensf \sevensc, \seventtsl, \seveni, \sevensy.
	(\resetmathfonts): Use them for math mode superscript.
	Vincent Lefevre reported that @var didn't work in superscript in

	purpose of \ifont and \syfont.

2017-12-26  Gavin Smith  <gavinsmith0123@gmail.com>

	anywhere.

2017-12-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\codequoteright, \codequoteleft): Check if we 
	are still in a monospace font in case we are inside @r, like
	@code{@r{`}}.  Report from rms.

2017-12-18  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\resetmathfonts): Revert last change.  Wrong 
	font used in footnote superscripts reported by Mohammad Akhlaghi.

2017-12-18  Bruno Haible  <bruno@clisp.org>

        * util/htmlxref.cnf: Use https for sourceware.org, puszcza.gnu.org.ua,
        gcc.gnu.org, www.complang.tuwien.ac.at, www.gmplib.org, www.gnupg.org,
        ftp.gwdg.de, www.nano-editor.org, cran.r-project.org, tug.org.
        Update info for avl, flex, myserver, readline.

2017-12-11  Gavin Smith  <gavinsmith0123@gmail.com>

	* util/htmlxref.cnf: Use https instead of http for links to 
	manuals on gnu.org.  Report from Bruno Haible.

2017-12-02  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\resetmathfonts): Define \scriptfont and 
	\scriptscriptfont in addition to \textfont.  Vincent Lefevre 
	reported that @var didn't work in superscript in math mode
	(bug-texinfo, 2017-11-27).

2017-11-17  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\enddoublecolums): Correct a conditional 
	checking \pagetotal.

2017-11-16  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\balancecolumns): If it appears that we have
	been called on to balance too much material for the final page 
	of the double column material, output some of it using 
	\doublecolumnout and leave remainder on current page.
	Otherwise, two problems occurred with the output: first, that
	the material on the last page of the index extended too low on 
	the page (see "Final page of index hard to balance" case in
	texinfo-tex-test.texi); and second, a blank page could occur 
	before the final page of the index (report from Arnold Robbins) 
	(this happened because of marks output in \savemarks and 
	\restoremarks).
	
	(\enddoublecolumns): Only change the output routine back to the 
	usual one and reset all the formatting variables if no extra 
	material has been added to the current page.  Otherwise, repeat.

2017-11-09  Gavin Smith  <gavinsmith0123@gmail.com>

	* doc/texinfo.tex (\pagesizes): Add one inch to height and width 
	so that text will still fit on the page if @pagesizes is used
	with a small width.  Report from Christopher Diemech
	2017-10-12.

2017-10-29  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi): Remove all calls to
	_register_command_arg that added elements to 
	'brace_command_contents' array.  Look at 'args' instead
	of 'brace_command_contents'.
	(_remove_empty_content_arguments): Do not check for a 
	'brace_command_contents' array.
	(module documentation section): Remove mention of
	brace_command_contents.
	* tp/Texinfo/Report.pm (_substitute): Do not look at
	'brace_command_contents' array.
	* tp/Texinfo/Convert/Converter.pm (_table_item_content_tree):
	Do not call _register_command_arg.

	The effect of this change is to make the parse tree less cyclic,
	which should make it easier to understand, for example when it 
	is printed.  It may also reduce memory use.

2017-10-29  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Convert/DocBook.pm (_convert):

	elements are defined to avoid creating them accidentally.

2017-10-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Convert/TexinfoXML.pm (_convert): Replace use
	of 'brace_command_contents' array in the 'extra' hash with
	the 'args' in the main tree.

2017-10-26  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_isolate_last_space): For 
	'brace_command_arg' only, save trailing spaces in 
	'spaces_after_argument' extra value instead of adding a 
	'spaces_at_end' element to the main tree.
	* tp/Texinfo/Convert/TexinfoXML.pm (_convert),
	* tp/Texinfo/Convert/Texinfo.pm (_expand_cmd_args_to_texi):
	Update to look at 'spaces_after_argument' after an argument to

	* tp/Texinfo/MiscXS/misc.c (xs_abort_empty_line): Update to
	match Perl implementation.
	* tp/Texinfo/Parser.pm (import): Re-enable XS overrides.

2017-10-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi): Rename reference to spaces 
	element from 'spaces_before_argument' to 'spaces_before_argument_elt'.
	(_abort_empty_line): Replace 'spaces_before_argument_elt' value
	with 'spaces_before_argument', a simple string value.
	(_close_current),
	(_parse_texi) <new line>: Call '_abort_empty_line' to remove 
	spaces element.

	* tp/Texinfo/Convert/Converter.pm
	(_collect_leading_trailing_spaces_arg),
	* tp/Texinfo/Convert/Texinfo.pm (convert, _expand_cmd_args_to_texi),
	* tp/Texinfo/Convert/TexinfoXML.pm (_leading_spaces_before_argument):
	Access 'spaces_before_argument' as a string value.

2017-09-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_abort_empty_line): Change code to
	keep track of which element refers to space element in its
	'extra' hash.  No functional change intended.

2017-09-25  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_abort_empty_line): Change the name of a 
	variable.  Use a variable to simplify the code.

2017-09-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_abort_empty_line): Remove
	'empty_spaces_before_argument' element from main tree.
	(import): Temporarily disable XS overrides.
	(_parse_texi) <new line>: Remove an 
	'empty_spaces_before_argument' element.
	Otherwise it will not be removed in '_abort_empty_line' because 
	a 'new_line' element is in the way.
	Do not call '_abort_empty_line' for a continuation with @ inside
	a def command, as this leads to an 'empty_spaces_before_argument'
	element being removed when it was not before.
	(close_current) <bracketed>: Remove an 
	'empty_spaces_before_argument' element.  This happens for some 
	cases of malformed input.

	* tp/Texinfo/Convert/Texinfo.pm (convert, _expand_cmd_args_to_texi):
	Check for a 'spaces_before_argument' extra value, and output the 
	spaces in it.
	* tp/Texinfo/Convert/TexinfoXML.pm (_leading_trailing_spaces_arg):
	Call _leading_spaces_before_argument to check for 
	'spaces_before_argument' extra value.
	
	* tp/t/test_tree_copy.t: Disable all tests, temporarily.
	* tp/Texinfo/Convert/Converter.pm
	(_collect_leading_trailing_spaces_arg): Check for 
	'spaces_before_argument' extra value.

	The effect of this change is to make the parse tree less cyclic,
	which should make it easier to understand.

2017-09-24  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi) <after ',' separating arguments>:
	Save 'spaces_before_argument' on element corresponding to argument.
	* tp/Texinfo/Convert/TexinfoXML.pm (_convert): Call 
	_leading_spaces_before_argument instead of _leading_spaces_arg.  
	This uses the 'spaces_before_argument' element we saved in 
	'_parse_texi'.

2017-09-22  Mathieu Lirzin  <mthl@gnu.org>

	* Makefile.am (CLEANFILES): Remove $(noinst_SCRIPTS) to
	keep 'pre-inst-env' when doing 'make clean'.

2017-09-22  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/Texinfo/Parser.pm (_parse_texi) <'{' seen>: Set 
	spaces_before_argument on element for the argument itself, not 
	for the element corresponding to the command, which is the 
	parent element.
	* tp/Texinfo/Convert/TexinfoXML.pm (_convert): Allow 'spaces' 
	attribute to be set for the element output for the first 
	argument to a brace command.

2017-09-22  Gavin Smith  <gavinsmith0123@gmail.com>

	* tp/maintain/change_perl_modules_version.pl: Account for
