Are you sure it used to work in this case?  If you could provide a
version where it worked we could try to look for the culprit.

I think you got it right: unbalanced "\begin" and "\end" are a
problem.  A couple of possible dirty workarounds: if possible, move
the offending code in a separate file in order not to break
indentation for the rest of the code; make "\newcommand" a verbatim
command (I don't remember it it's possible to do it for two-argument
macros, though).  In addition, can't you do the conditional test on
the argument of "\begin{tabular}" only and call "\begin{tabular}" just

In any case, I'm not sure it's good LaTeX-style to define commands
that fiddle with "\begin" and "\end".  Shouldn't this be a task of
