Erm, in Darcs 2 rollback records a new inverse patch. That is, it's
darcs diff -p foo | patch -p1 -R
darcs record -m 'rollback foo'
I would have thought that a rolled-back transaction (in database terms)
is closer to obliterate, since the end result is that you have no record
of that transcation, rather than X + -X = 0. Admittedly, IANADBA.
