What was the recipe that lead to a problem?
revert 1fa39e1f953434, create an equation array and enter \hline in any cell
with the keyboard. This will produce a horizontal line, but undo does not
work afterwards. If you only revert the undo group part of 1fa39e1f953434,
and keep the changes in InsetMathGrid::interpretString(), undo will work,
but two undo entries are produced (only the top of the undo stack will
change somehing if executed).
Here is what I would do after reverting 1fa39e1f953434. Does that seem
to work for you? THe idea is to only record undo (inset) once before the
insertion of the unknown inset.
