[l2h] multline environment numbering

[José Rincón]

This is probably either known or has a simple solution, but I couldn't find
anything about it searching in the internet.

When converting the document you will find below, the numbering of equations
that come after a multline environment is wrong. The multline equation seems 
to be ignored, so the next equation is still numbered as (1). However, the
hyperlinks still point to the right place.

I have a web page where you can find the result after conversion:
http://www.ugr.es/local/ozarfreo/tmp/prueba/index.html
You can also find in http://www.ugr.es/local/ozarfreo/tmp/ the tex source and 
any other output that might be of help (the converted file was prueba.tex).

Thanks!

%% This is the LaTeX source:
\documentclass[12pt]{article}

\usepackage{amsmath}

\begin{document}

Here goes a multline environment:
\begin{multline}\label{eq:1}
  x + 99999999999999999 x =\\
  100000000000000000 x
\end{multline}
And here an equation:
\begin{equation}
  \label{eq:2}
  a = \pi
\end{equation}
Referring to the first one, one gets this: (\ref{eq:1}).

\end{document}
