Padding in aligned environment not correct after fourth column

[siegfriedzoetzsche]

Consider a latex file aligned.tex:

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{equation}
  \begin{aligned}
    a & = b & c & = d & e & = f \\
  \end{aligned}
\end{equation}
\end{document}

with six columns representing three separate equations on the same line.

When running latexml (LaTeXML version 0.8.2; revision 48de2c4) with

latexml --strict --verbose --nocomments --destination=aligned-latexml.xml aligned.tex

a padding is added to the every third column ('c' and '= f' in the example):

aligned-latexml.xml:

[...]

      </Math></td>
    <td align="left"><Math tex="\displaystyle\hskip 10.0pt=f" text="absent = f" xml:id="S0.E1X.m9">

[...]

The expected behavior would be to add a padding to every odd column except the first.

Harumph; a cut-n-paste error, I think. I must have copied the column pattern from eqnarray? Anyway, fixed now in the repo; thanks for the report!
