o time.template:time_common please help me fill out the documentation,
	on the different subjects.

o please explain the following variables to me:
		nostat
		recognize_only_executables
		afsuser
		visiblebell <-- does this work?
		
o please explain the difference between the following values to the variable
	matchbeep: ambiguous, notunique

o can anyone tell me why it is smart to have ., -, and _ as word
	separator in the variable complete?
o In the tcsh manual it says that the default for echo_style is both, is
	that correct?  It seems to me that on our system, it is bsd.
o In the tcsh manual it says that the default for prompt3 is
	"CORRECT>%R	(y|n|e)? ".  Isn't it: "CORRECT>%R (y|n|e|a)? "
o bindkey doesn't seem to work for me:
	If I want to bind kill-line to C-xC-x (twice ctrl-X), then I should
	write as follows: bindkey -b C-xC-x  This will, however, bind kill-line
	to C-x instead.  Am I doing something wrong, or is it a bug in tcsh?
o It seems to me that dirs -S works unless it is used with the variable
	savedirs.  Try to pushd some dirs, set the variable savedirs, and then
	exit the shell.  Finally look in the file ~/.cshdirs.  Does it work?
o can anyone tell me what the variable autocorrect does?  I don't understand
	what the manual says.
