Good question.  It is the whole point of cherry-pick that
CHERRY_PICK_HEAD and the current HEAD may not have any meaningful
ancestry relationship, so yes, it is questionable to use the same
logic for "log --merge" between HEAD...CHERRY_PICK_HEAD, while using
HEAD...MERGE_HEAD does make perfect sense.
