I have impression that you make several changes which go beyond
generating LaTeX. In particular, AFAICS 'array' works fine
LaTeX and I do not see why you replace it by 'pmatrix'.
Also, have you checked that 'ungroup' handles each case correctly?
In partucluar, are you sure that no construct will generate empty
group (AFAICS 'ungroup' would colapse empty group to nothing which
changes semantics).
