Subject:    [PATCH 3/8] revert: refactor code into a do_pick_commit() function

This is needed because we are going to make it possible
to cherry-pick many commits instead of just one in the following
commits. And we will be able to do that by just calling
do_pick_commit() once for each commit to cherry-pick.
