[Bug-AUCTeX] AUCTeX and xypic problems.

[Mark Dickinson]

I'm having trouble generating previews for a document that uses the
xypic package for generating commutative diagrams.  Here's a minimal
example.

-----------------------
\documentclass{article}
\usepackage[all]{xy}

\begin{document}

\begin{figure}
address@hidden & B}
\end{figure}

\end{document}
-----------------------

After running C-c C-p C-d on this document, I just get a blank line
where I was expecting to see a preview for the figure.  The TeX output
buffer shows a series of errors; here's an excerpt starting from the
first error, which seems to be related to the use of address@hidden in the
matrix. (The full output is included at the end of this message.)

l.6 \begin{figure}

<xymatrix

Runaway argument?
h\dir [r]
! Paragraph ended before \next@ was complete.
<to be read again>
                   \par
l.7 address@hidden & B}

! Missing $ inserted.
<inserted text>
                $
----------------------

Is there any way to fix this?
