#115 Coloring issues with LaTeX
I know, TeX/LaTeX is probably one of the harder formats to colorize correctly, but overall colorer does quite a good job there.
Since, $ starts math mode in LaTeX nad thus appropriate highlighting in Colorer and it can be used nearly everywhere, especially in code, this can lead to the following quirk:
\documentclass{article}
\begin{document}
\begin{verbatim}
$var = "blah";
\end{verbatim}
\end{document}
where math mode extends beyond the verbatim block, same works for lstlisting as well and for $$, \[ or \(. However,
\verb#$#
does work correctly and won't trigger math mode highlighting. I've looked into the HRC but couldn't come up with a quick fix to this problem. Solution would be, to disable different highlighting modes in verbatim and similar blocks (lstlisting is one of them), though I'm unable to do that :)

Please report any other TeX issues if find them. I'm now tightly working with TeX so trying to fix everything on the way ;)

\begin{lstlisting}
s = string.gsub(s, "\\(%a+){(.-)}", "<%1>%2</%1>")
\end{lstlisting}
for instance still trips. I don't know how much semantic highlighting you desire, especially due to the multitude of packages out there that possibly do something nasty with commands. But I think I saw lstlisting mentioned elsewhere in the hrc, so maybe you give some commonly used commands special behaviour.
