Not really, that's why said that I *may* have used PREV once, but not
more than once.

The only symbolic name I can think of that would be useful but doesn't
currently exist might be called "ROOT" or "ORIGIN" -- the source
revision of a branch or tag. That would be very handy with merging.
Another symbolic name that would become useful when merge tracking
becomes real would be the last rev merged (i.e., the start rev of a
subsequent merge).
