[XeTeX] Problem with positioning of harakats on the lam-alif ligature with ArabXeTeX

[Edin Salkovic]

Hi all,

There's a problem (bug?) with ArabXeTeX positioning of harakats on the
lam-alif ligature.  Here's a minimal TeX file illustrating the
problem.

\documentclass{article}
%\usepackage{xltxtra}
\usepackage{arabxetex}
\newfontfamily{\arabicfont}[Script=Arabic,Scale=1.5]{Scheherazade}
\newcommand{\ar}[1]{\textarab[utf]{#1}}
%\newcommand{\ar}[1]{\RL{\arabicfont#1}}
\begin{document}
\ar{الْأَوَّل}
\end{document}

Commented out are the lines that display the text correctly without
using ArabXeTeX.
