[Bug-AUCTeX] 2014-02-10; \intertext-macro not properly indented inside align-environments

[Simon Campese]

Hello,

I just recognized that when typing mathematics inside align or align*
environments (which are provided by the amsmath package), \intertext
macros are not recognized as being typeset on a new line by auctex. For example,
autoindenting the code 

\begin{align*}
F_1 &= 1 \\
F_2 &= 2
\intertext{and}
F_{n+1} &= (n+1) F_n 
\end{align*}

yields

\begin{align*}
  F_1 &= 1 \\
  F_2 &= 2
        \intertext{and}
        F_{n+1} &= (n+1) F_n 
\end{align*}

instead of

\begin{align*}
  F_1 &= 1 \\
  F_2 &= 2
  \intertext{and}
  F_{n+1} &= (n+1) F_n 
\end{align*}

Unfortunately I don't know enough Elisp to fix this myself but I guess
that the parser just checks for '\\' to recognize a new line and a
simple cases statement including '\intertext' has to be added.
And while you're at it, I guess the same is true for '\shortintertext'
from the mathtools package. 


Best,

Simon
