Package: auctex
Version: 11.11-3
Severity: grave

Hi,

I was writing an article when I have suddenly discovered that auctex was
adding some parentheses in my equations. Here is the example:

=======================================================================
\documentclass{article}
\usepackage{amsmath}

\newenvironment{LinearProgram}[2][Maximiser]{%
  \begin{equation}%
    \def\@currentlabel{\theequation}
    \begin{array}{l}%
      \textsc{#1} \displaystyle #2, \\%
      \textsc{sous les contraintes}\\%
      \begin{cases}
      }{%
      \end{cases}
    \end{array}
  \end{equation}%
}
\newcounter{subcounstraints}[equation]
\makeatletter
\newcommand{\EquationsNumberedMacro}[1]{%
  \setcounter{subcounstraints}{0}
  \renewcommand{\thesubcounstraints}{\theequation\alph{subcounstraints}}
  \def\set@counstraintscounter{
    \refstepcounter{subcounstraints}%
    \xdef\@currentlabel{\thesubcounstraints}%
    \tagform@{\thesubcounstraints}%
  }
  \def\n{\\\set@counstraintscounter\quad&}
  \begin{aligned}%
    \set@counstraintscounter\quad&
    #1
  \end{aligned}%
}
\newcommand{\eqnlabel}[1]{\xdef\@currentlabel{\theequation}\ltx@label{#1}}
\newcommand{\cnstslabel}[1]{\ltx@label{#1}}
\makeatother


\begin{document}

\begin{LinearProgram}{T_{f}}
  (5)~\sum_{j=1}^{p} x_{i,j} = 1 & 1 \leq i \leq p\\
  (6)~\sum_{i=1}^{p} x_{1,i} (g_i + \alpha_i G_i + \alpha_i w_i) \leq T_f
  & \text{(première communication)}\\
  (7)~\sum_{k=1}^{j-1} \sum_{i=1}^{p} x_{k,i} (g_i + \alpha_i G_i)
  & 2 \leq j \leq p \text{ ($j\eme$ communication)}\\
  ~~~~~~+ \sum_{i=1}^{p} x_{j,i} (g_i + \alpha_i G_i + \alpha_i w_i) \leq T_f\\
\end{LinearProgram}

\end{document}
=======================================================================

When adding a space character at the end of the las line of my equations,
here is the way it is changed:

  ~~~~~~+ \sum_{i=1}^{p} x_{j,i} (g_i + \alpha_i G_i + \alpha_i w_i)
  (\leq T_f\\ 

 /|\ 
  |
  
 Here !

It is very weird, reproducible and, imho, particularly vicious.

Hope you will find where it comes from. 

Good luck.

Hello,

Thanks for your interest in improving Debian, and sorry that the bugs
were not fully resolved or closed in due time.

emacs21 packages have been removed from testing in 2009 [1], not
present even in the current stable.  Consequently, these bugs are now
orphan (without maintainer assigned) so they probably will not be
attended/noticed further.

[1] http://packages.qa.debian.org/e/emacs21.html

The bugs deemed valid are going to be verified and reassigned, but the
current bugs that I'm closing now are very ancient (more than 10 years
sometimes) and marked as fixed-upstream years ago, with no recent
input, and are supposed to be fixed in emacs22 at the latest.

Please comment if you want think that some of the raised questions are
still pending and need to be addressed differently (e.g., reassigned
to other packages, etc.).

Cheers.
