Re: Syntax table issues

I'm working this week and next on improving the recent (or
not-so-recent) syntax table changes in an effort to get them ready for
a 21.4 release.
I've heard for awhile that the syntax table performance in XEmacs has
been lacking since the patch was applied, but I haven't been able to
get enough details to actually track down the problem.
If anyone can give me any information on a _reproducible_ case
(preferably with -vanilla enabled) that illustrates bugs or poor
performance with the syntax table code, I'd appreciate it tremendously.
Thanks very much for your time and patience.
1. Start up xemacs -vanilla
2. Add the following text (comment included) into the *scratch* buffer:
;; This buffer is for notes you don't want to save, and for Lisp evaluation.
;; If you want to create a file, first visit that file with C-x C-f,
;; then enter the text in that file's own buffer. (C-x is the standard
;; XEmacs abbreviation for `Control+x', i.e. hold down the Control key
;; while hitting the x key.)
;;
;; For Lisp evaluation, type an expression, move to the end and hit C-j.
(when (or (featurep 'xemacs) window-system)
(require 'mic-paren)
(setq paren-sexp-mode t)
(set (if (boundp 'paren-face) 'paren-face 'paren-match-face) 'bold)
(and (fboundp 'paren-activate) (paren-activate)))
3. Evaluate the buffer.
4. Put the cursor after the closing paren in 'the x key.)' You will
notice that, even though the parens are balanced and in a comment,
the closing paren turns yellow, indicating a matching open paren
can not be found.
Thanks, Matt.
HTH,
