[TxMt] LaTeX Syntax coloring problem

[Kai von Fintel]

The minimal test case below shows that something in the parsing of the
newenvironment command is throwing off the syntax coloring by the
LaTeX bundle, at least on my system (TM 1.5.7 1464 on Leopard). The
text in the document is incorrectly parsed as being in a math
environment.

\documentclass{article}

\usepackage{amsmath}

\newenvironment{choice}
     {\left\lbrace\begin{gathered}}
     {\end{gathered}\right\rbrace}

\begin{document}

Text incorrectly parsed as being in a math environment.

\end{document}

-----

Any ideas of how to fix the parsing?
