[AUCTeX] Wrong Placement of \end{tabularx}

[Arash Esbati]

Hi,

Having `AUCTeX-date "2014-10-02"' installed, I hit 

`C-c C-e tabularx RET RET RET lrlX RET'

and get the result shown below: Note the 2 spaces
before \end{tabularx}.  Is this a bug?  It works fine for
tabular-environment.

===========================

\begin{tabular}{lrl}
  &&
\end{tabular}

\begin{tabularx}{1.0\linewidth}{lrlX}
  &&
  \end{tabularx}
^^
===========================

Best, Arash
