just comments fontified in latex mode?

[Joe Corneli]

I'm using the same .emacs as I used on my (broken) iBook, now working
on a linux machine.  Just the comments are fontified by font-lock in
my TeX files.  I asked my system administrator about this and he
suggested using the hilit-LaTeX package.  It highlights stuff, but I
didn't like the way it behaved (uses different colors, doesn't
automatically rehighlight new $$'s, etc.).  Can anyone tell me how to
get normal font-lock working again?

Try running emacs with:

$ emacs -q

Now M-x load-file RET .emacs (or the path to your .emacs) RET

If things aren't messed up anymore it means your sysadmin has something
in the site .emacs (I forget the technical term) and it's causing the
problem.

I'd suggest _not_ using hilit-LaTeX and I'm the one who wrote it.
The hilit19 interface is obsolete.

It should just work.

You might also give font-latex.el a try.  It's my hilit-LaTeX
replacement and is used in AUC-TeX (but can be used outside of AUC-TeX):

Or better yet

   emacs -q --no-site-file

in case the problem is in site-start.el.

And if things still are messed up? :) 

If this is a clue, even though I can get comments to appear in red in
a LaTeX file, I have to turn on font-lock-mode manually to get them
to appear.  (Which of course wasn't the case before.)

By the way, just to check, I loaded the *exact* same .emacs as I was
running on the broken laptop, and no improvement. Still have nice
colors in e.g. mail-mode, emacs-lisp-mode, etc.  But not in any latex
files.

Also note, same behavior is seen when I run font-lock-mode from emacs
-q in a latex buffer (though a different color is used for comments).
I was pretty sure that the default behavior of font-lock-mode was more
complicated than this.

Well the idea is simple.  Emacs loads the .emacs for the
computer/server/site and then your .emacs.  I was curious whether or not
the site .emacs what causing the problems.  Try loading emacs with just
the -q.  If you're still having problems there's something you need to
add to your .emacs that was probably in the .emacs of your last
computer/server.  If you're not having problems you need to remove
something from your .emacs.  Best bet is to add things in line by line.

Old AUCTeX do not show font-lock in Emacs-21.
Can't remember when this was fixed.  AUCTeX 11 maybe?

I have the opposite problem. If I put a comment in a latex file, all
the text following the comment is highlighted with the comment font
colour until there is a ^L and then normal fontification works.

I've observed this on two Debian boxes - one running Debian Testing
(Sarge) and the other running Debian Unstable (Sid). The Debian
unstable versions are 

GNU Emacs 21.3.1
AucTex 11.13-1

I get the same results with emacs -q - don't know about emacs
--no-site-file as AucTex is initialized via the site-start.el, but
I've not modified it from the default Debian scripts.
