The earlier "--keep-redundant-commit" series broke "cherry-pick" that is given a commit whose change is already in the current history. Such a cherry-pick would result in an empty change, and should stop with an error, telling the user that conflict resolution may have made the result empty (which is exactly what is happening), but we silently dropped the change on the floor without any message nor non-zero exit code.
