Reversion of \multicolumn in array environment

[molke-productions]

Using \multicolumn in array (or matrix, …) with version 0.8.6 does not lead to an error anymore, and MathML seems to be fine, but the TeX code and the generated image are not quite right (replacing the column span just with \hfil, probably due to c alignment).

The conversion in array-multicol.zip was done with

latexmlc -presentationmathml --mathimages --mathtex --destination=test.xml test.tex
