Bug#95980: black borders on all images

[frank@kuesterei.ch (Frank Küster)]

Hi Hilmar,

this is another time that we ran into the "nnn-forwarded doesn't send
copies to maintainer" problem.

I have yet made a minimal document, 
\documentclass{article}
\usepackage{amsmath} 

\begin{document}

\fbox{%
  $\begin{matrix}%
    x & y \\ \hline%
  \end{matrix}$%
}

\end{document}

and forwarded this to the amsmath people. Unfortunately, the order of
the mails in this bug seems to be totally messed up. A short summary:

- \hline is not really intended to work in the matrix environment (Chris
  Rowley) 

- The reason is that the matrix is "trimmed" by \arraycolsep to prevent
  otherwise unwanted space (Chris Rowley)

- A fix has been proposed by Ross Moore to add a hook to be able to
  change this. So far, Chris has not reacted on this.

I will ask again, this time Cc-ing debian-tetex-maint.

Bye, Frank
