Yes. The other one was a bit redundant, I admit.

I took the regular expression from `LaTeX-env-contents'.  This may need
to be tweaked as well?

Thank you for the comments.  I've made attempts at getting this to work,
and I have a basic thing working (with a better regular expression, that
was tested on a few random strings), but I'm somewhat in doubt of all
the tests done in LaTeX-current-environment, and whether I can't just
check for `TeX-in-commented-line' (this is what I currently just do, and
it appears to work quite well)?  In particular, I'm confused about what
syntactic comments are.  A very small example would be highly appreciated.

Tasilo: You missed to add me in the CC to your reply to listings.diff
I'll write back with a ChangeLog entry in the weekend, and will fix the
couple of things that I noticed were wrong in the patch (newlines, and a
"" inside TeX-add-symbols).
