Developments of the last 48 hours:

1. Andreas Schwab sent me a patch that uses commitids wherever the history
   has them - this makes all the time-skew problems go away.  I added code
   to warn if commitids aren't present, so users will get a clear indication
   of when time-skew problems might bite them versus when that is happily
   impossible.

2. I've scrapped a lot of obsolete code and options.  The repo head
   version uses what used to be called cvs-direct mode all the time
   now; it works, and the effect on performance is major.  This also
   means that cvsps doesn't need to use any local CVS commands or even
   have CVS installed where it runs.

That could be.  But right now cvsps has one significant advantage over
cvs2git (which parsecvs might share) - it's *blazingly* fast.  So fast
that I scrapped all the local-caching logic; there seems no point to it at
today's network speeds, and that's one less layer of complications to
go wrong.

I've removed a couple hundred lines of code and the program works
better and faster than it did before.  That's having a good day!
