The derivation path can be described, most inadequately, as "long and
twisty".  The modification log is several hundred lines long.  I took a
quick look through it and found nothing specifically identified as
fixing regular-expression bugs, but there are enough slightly-mysterious
references to cleanups and such that it's hard to be sure.

It would be rather difficult to recover an original V6 source, and I
probably couldn't make it run on a Sun to check.  I may be able to give
a definitive answer about V7 next week.
