When the end-user action is "git cherry-pick A..B", shouldn't
the rewrite hook be called with "cherry-pick" not "rebase" as its
first argument?
More importantly, doesn't "git revert A..B" also trigger the
codepath for [4/8] and hence this function?
I think [3/8] --skip-empty makes sense also for revert, but I do not
think this one does as-is. As what [4/8] introduces is a record of
"rewrite", the patch does not make sense either. These two steps
would want to limit themselves to cherry-pick only, no?
