Thank you for the insight into theory, however the practical results
are annoying. For example, running mergemaster has become a nightmare.
It considers every file to be changed (unless you do some black magic
with DIFF_OPTIONS to ignore \$FreeBSD:.*\$). 

BTW what does cvsup (in CVS mode) do with an RCS file to which only a
branch tag has been added? How does it mirror such a change? Just
curious.
