#1185 Emaxima package with preview option breaks inline preview

[Henrik Wallin]

When creating a latex document with inlined math in EMaxima mode, generating a preview in the emacs buffer for the document (C-c C-p C-d) will not generate previews for the inlined math in the text if the [preview] option has been given to \usepackage{emaxima}.

Example document:
%<example>
\documentclass{article}
\usepackage[preview]{emaxima}
\begin{document}
Inlined math test $2^N$, then maxima formula test:

\begin{maxima}
'sin(x^2);
\maximaoutput*
\m \sin x^2 \\ \end{maxima}
\end{document}
%</example>

Typing [C-c C-p C-d] in emacs (preview-document) will create previews for the maxima outputs, but not for $2^N$. On the other hand, removing [preview] from the line \usepackage[preview]{emaxima} and executing preview-document will render 2^N correctly (but not the maxima math of course).

I use maxima-5.10.0 with emaxima.lisp, emaxima.el and emaxima.sty from maxima CVS.
