Hmpf, it should work if `or' instead of `and' is used.

Okay, I applied the patches.  I don't intend to use the solution with
`skip-chars-backward' because yours seems to work on both Emacs and
XEmacs.  It is just that I am a bit suspicious regarding multi-line
regexps.  I seem to recall that they are not working all the time but
cannot give an example where this actually is true.  Maybe this was
formerly the case and now is fixed.  Whatever.

Thanks for the contribution.

BTW, in case you are intending to continue contributing to AUCTeX you
should consider asking David for CVS access.  It will make the whole
process of applying patches, testing etc. much easier.  (At least for
me. (c;)
