	makediff: cleanup using begingroup/endgroup

This seemed like a good idea originally: replace perl hacks with
tex hacks. However adding \begingroup and \endgroup within macros
used by latex-diff breaks its assumption that these are low level
tex and can be used in arbitrary situations, e.g.  cross the
boundaries of environments, use mis-matching begin and end
instructions (DIFaddbegin with DIFaddendFL), etc.

Let's go back to the original work-around:

    work around xetex bug

    Too many \color directives produce corrupted output
    and this warning:
    WARNING ** Color stack overflow. Just ignore.

    Use script to reduce # of these directives.
