[AUCTeX] Math mode in newenvironment not recognized

[Florian Lindner]

Hello,

I have a environment:

\newenvironment{formelgruppe}[1]{
  \boxedminipage{1.0\linewidth} \emph{\Large{#1}} \csname align* 
\endcsname}
{\csname endalign*\endcsname \endboxedminipage \vspace{1cm}}

Used like that

\begin{formelgruppe}{Stoffgesetze für ideale Gase}
   pv &= RT \Longleftrightarrow pV = mRT
\end{formelgruppe}

As you see there is math in the environment. Auctex does not get this  
and treats like text (though preview-latex renders the formulas). Can  
I give auctex a hint that it should treat the content of formelgruppe  
like math?

Another minor things I would like to optimize is that auctex positions  
the cursur between the brackets of the environment argument (marked  
with x here) when using C-c C-e. Or even better asks for it!  
(something like: "first argument:" would be perfect ok).

\begin{formelgruppe}{x}

\end{formelgruppe}

Any way to achieve hat?

Thanks,

Florian
