Subject: 23.2; latex-close-block indenting \end{verbatim} incorrectly
Date: Thu, 07 Jun 2012 14:14:04 +0200

    C-x C-f /tmp/foo.text

Enter

    \begin{verbatim} RET SPC SPC SPC hello RET C-c C-e

and the resulting \end{verbatim} is indented three spaces instead of in
column 0 as it should be.

The problem does not manifest with \begin{quote}.

I presume you meant "foo.tex" ;-)

Yes, verbatim is special in LaTeX, and hence so it is in latex-mode.
The bug actually seems to require you be at EOB when hitting C-c C-e.
I've installed the patch below which seems to fix the root cause.
