[l2h] missing braces

[Vadim Yu. Radionov]

Hello!

I compiled TeX file containing

$$
\overset{\text{insert\strut}}{
\begin{pmatrix}
u= 2-3x^3\\ u' = -9x^2,\ k = -\frac{1}{9}
\end{pmatrix}}
$$

but latex2html wrote only

{\newpage\clearpage
\lthtmlinlinemathA{tex2html_wrap_indisplay275}%
$\displaystyle \overset{\text{insert\strut}}\begin{pmatrix}
u= 2-3x^3\\  u' = -9x^2,\  k = -\frac{1}{9}
\end{pmatrix}$%
\lthtmlindisplaymathZ
\lthtmlcheckvsize\clearpage}

to images.tex (missing braces around pmatrix environment, so latex 
fails).
