[Bug-AUCTeX] 11.83; Fontification and folding bug

[Patrick Drechsler]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.

Be sure to consult the FAQ section in the manual before submitting
a bug report.  If the bug (or problem) is triggered by a specific
(La)TeX file, you should try to produce a minimal sample file
showing the problem and include it in your report.

Your bug report will be posted to the AUCTeX bug reporting list.

0. Activate folding and syntax-highlighting in AUCTeX.
1. Start Emacs. Create tex file (ie fold-highlight.tex) using `C-x C-f'.
2. Enter this minimal example:

==============================
\documentclass{article}

\begin{document}

\section{Foo}
\label{sec:foo}


\section{Bar}
\label{sec:bar}


\end{document}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:
==============================

This should look like (highlighting-wrong):

What I was expecting is (highlighting-correct):

http://img81.imageshack.us/img81/9710/shot002headlinesyesjs1.png

I can accomplish this by moving the cursor to the beginning of the 
"\section" lines and expanding the folded text by pressing arrow-right. 
And then arrow-left again to see the correct highlighting.

I am using the same settings as described in my previous bug report 
concerning Noweb files (see: 
http://article.gmane.org/gmane.emacs.auctex.bugs/847)

Any ideas?

BTW: Can I attach little screenshots like these to my bug report in the 
future or will they be stripped from the message?
