Hi
I deemed it an especially good idea to have function which is
searching something in a buffer when there are changes to the content.
(GNU Emacs 22.0.95.1 (i486-pc-linux-gnu, GTK+ Version 2.8.20) of
2007-03-02 on pacem, modified by Debian.)
When I install such a function in the following way (for example in
the *scratch* buffer):
$ emacs -Q -D
(defun bla ( &optional a b c) ;dummy variables
(interactive)
(save-excursion
(re-search-forward "a" nil 'noerror)))
(add-hook 'after-change-functions 'bla nil t)
and I try to M-/ something at the buffer beginning, the cursor does
not remain after the expansion but skips somewhere into the buffer.
I'm not sure whether this is a bug of M-/ or this is just a stupid
approach to have such an functionality after a buffer change? It
would be nice if you could give me some advice before I submit a
possibly unnecessary bug report.

I'm very, I got the wrong news group. The original message was meant
exclusively for emacs.help and not (yet) for this list.

You probably need to save-match-data as well.
