[XeTeX] Unwanted Extra Par

[Vafa Khalighi]

If I created a simple document as

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\documentclass{minimal}

\makeatletter

\TeXXeTstate=1

\def\equation{\beginL$$\refstepcounter{equation}}

\def\endequation{\eqno \hbox{\@eqnnum}$$\endL\@ignoretrue}

\makeatother

\begin{document}

\begin{equation}

1+1=2

\end{equation}

\begin{equation}

1+1=2

\end{equation}

\begin{equation}

1+1=2

\end{equation}

\begin{equation}

1+1=2

\end{equation}

\end{document}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Just the \beginL and \endL that I have put before and after $$ respectively
casuses a new par between these equations.  My question is, is there any way
that I could remove that extra par except by having \vskip -\baselineskip?
And I do not think that is a good idea for removing the extra par.

Thanks
