I would have expected the sanity check for incoming arguments would be done at the very beginning, but I guess it is OK (the same comment applies to all the others).

The addition to "git_rebase" does not need this "if must-fail was given, return early" because it was at the end of the helper, but here we have some post procedure that relies on the checkout to be successful, so after correctly failing the checkout we return. It is somewhat tricky, but OK. The same for the next one.

Looking good. Will replace. Thanks.
