I tested it on a real cvs checked out module and just as I suspected
after rsyncing from the buffer directory where diff reports no
differnces.  Then try cvs commit.   Cvs demands every file be
commited.  Surely this is not what is supposed to happen.

rsync man pages indicate rsync will work nicely with cvs.  Further
with rsyncs elaborate algorythems for testing for differences why are
I seeing the massive transfer when files are the same?
