Hi,
the following MWE compiles like a charm from a LaTeX point of view but
has a syntax highlighting problem from an AUCTeX point of view: because
the character just after the 1st `\begin{lstlisting}' is not what is
expected (not a `['):
1. what follows until the 1st `\end{lstlisting}' is not considered as
a listing (not on a yellow background),
2. this 1st `\end{lstlisting}' and what follows is considered as
a listing (on a yellow background) until the next `\begin{lstlisting}',
3. etc.
Hence, after the 1st `\begin{lstlisting}', listing and not listing
regions are inverted.
Is there a way to circumvent this trouble?
Thanks in anticipation.
