[l2h] Cannot get htmlonly to work in a macro

[Francois Felix Ingrand]

The following macro used to work.... but now breaks latex on the htmlonly
part.

! LaTeX Error: Not in outer par mode.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              
                                                  
l.133 \figuregif[scale=0.5]{mo
                              ve-valve-op-exp}{Example of a OP}{fig-proc1-fig}
You've lost some text.  Try typing  <return>  to proceed.
If that doesn't work, type  X <return>  to quit.

Any way to fix it?

\newcommand{\figuregif}[4][]%

\begin{figure}

\begin{latexonly}

\includegraphics[#1]{#2.ps}

\end{latexonly}
\begin{htmlonly}
\htmladdimg[center]{gif/#2.gif}
\end{htmlonly}
\caption{#3}
