What is special is that it's the last transaction and can be done
basically for free with what we already have to do to manage aborting
that transaction. Also note that one level of rollback doesn't lose any
data beyond your commit message, as the committed data is generally
either still in your working directory or the server you pulled from,
while multiple rollback can lose intermediate changes.

Probably because I categorically stated about 5 years ago that I didn't
want it. See clone -r for a safe, easy alternative.
