regex bug with pattern "\\*/" matching end of buffer */ |

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.
Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.
In GNU Emacs 21.3.1 (i686-pc-linux-gnu, X toolkit)
of 2005-03-24 on monster
configured using `configure --prefix=/home/geoff/i686
--with-toolkit-scroll-bars'
Important settings:
value of $LC_ALL: C
value of $LC_COLLATE: nil
value of $LC_CTYPE: nil
value of $LC_MESSAGES: nil
value of $LC_MONETARY: nil
value of $LC_NUMERIC: nil
value of $LC_TIME: nil
value of $LANG: en_US.UTF-8
locale-coding-system: nil
default-enable-multibyte-characters: t
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
If I have a file with the following line (no trailing space):
char ch; /* sample comment */
then I put the cursor on it and execute the following elisp code:
(save-restriction
(narrow-to-region (progn (beginning-of-line) (point))
(progn (end-of-line) (point)))
(goto-char (point-min))
(while (and (re-search-forward "/\\*" nil t) (not (eobp)))
(replace-match "/-*" nil nil))
(goto-char (point-min))
(while (and (re-search-forward "\\*/" nil t) (not (eobp)))
(replace-match "*-/" nil nil)))
it will give me the following line as the result:
char ch; /-* sample comment */
In contrast, what I expect is this:
char ch; /-* sample comment *-/
If I add a trailing space, then I get appropriate behavior.
Regards,
Geoff Odhner
