Can someone use a process of cutting the regexp set repeatedly in half
until they find the regexp which hilights these correctly in Emacs but
not in XEmacs.  It's rather impossible to track down a regexp bug w/o a
sample.  Although, I'm pretty sure that the 19.15 regex.c is mostly
synched with 19.34's.
