[AUCTeX] [bug] TeX file does not inherit styles from master

[Leo]

Hi there,

I think I discovered a bug in AUCTeX.

The master file m.tex:
----------------
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\include{s}
\end{document}
----------------

The slave file s.tex:
----------------
\section{What's wrong?}

Test styles.
%%% Local Variables: 
%%% mode: latex
%%% TeX-master: "m"
%%% End: 
----------------

In the master file C-c C-e has completion /align/ available but not in
the slave file.

This is tested in version 2009-01-14.

Best wishes,
