revert: allow single-pick in the middle of cherry-pick sequence
After messing up a difficult conflict resolution in the middle of a
cherry-pick sequence, it can be useful to be able to
git checkout HEAD . && git cherry-pick that-one-commit
to restart the conflict resolution. The current code however errors out
saying that another cherry-pick is already in progress.
