[l2h] problem for \framebox in picture environment

I found a problem for \framebox in picture environment.

\framebox is used as the form "\framebox[w][p]{text}" usually. 
Moreover, it is used as the form "\framebox(w,h)[p]{text}" to 
draw a rectangle in picture mode.

When the latex2html makes images.tex for \framebox, the first 
form is inserted correctly, but the second form is done 
incorrectly.

For example, for the LaTeX source:

  \begin{figure}[ht]
      \begin{picture}(200,150)(0,0)
        \put(40,40){\framebox(140,100){}}
      \end{picture}
  \end{figure}
  Well, another framebox \framebox[7em][l]{sample}.

images.tex will be:

  {\newpage\clearpage
  \lthtmlfigureA{figure3}%
  \begin{figure}  \begin{picture}(200,150)(0,0)
      \put(40,40){\framebox{(}140,100){}}
  \end{picture}
  \end{figure}%
  \lthtmlfigureZ
  \lthtmlcheckvsize\clearpage}

  {\newpage\clearpage
  \lthtmlpictureA{tex2html_wrap21}%
  \framebox[7em][l]{sample}%
  \lthtmlpictureZ
  \lthtmlcheckvsize\clearpage}

The first form "\framebox(140,100){}" is translated to illegal 
code "\framebox{(}140,100){}}". This translation may be done 
by &wrap_cmd_framebox, which is made in &process_commands_in_tex:

 L13755 # $body .= '$args .= "$`$&" if s/$next_pair_rx//o;'."\n";
 L13756   $body .= '$args .= join("","{", &missing_braces, "}") unless ('."\n";
 L13757   $body .= '  (s/$next_pair_pr_rx/$args.=$`.$&;""/es)'."\n";
 L13758   $body .= '  ||(s/$next_pair_rx/$args.=$`.$&;""/es));'."\n";

When I use the code L13755 instead of L13756-13758, it does not
occur the problem. But I don't know whether this is correct 
solution.
