math bug

Hi!

I found a bug in the math handling code in the current cvs version.
The bug is not present in 1.9.15 and I don't know about 1.9.16a.
When using the EQ field, after a \left command all variables in an
equation are not italicized.

The bug is demonstrated by the following latex document:

\documentclass{article}
\begin{document}
$$
z=3D\cos\left(x+y\right)+w
$$
\end{document}

After conversion to RTF, x, y and w are typeset in a roman font.
This is due to the fact that MonitorFontChanges() misinterprets the
bracket switch \b as a font changing command.

I fixed the bug by this patch:

                 MonitorFontChanges(text);
         }
         last=3D *text;


Let me thank you for this nice piece of software.
