Hmm, ok, thanks for investigation!

But then, about this empty commit handling behavior by rebase.
Low-level developer in me understands the current behavior - if we
expect changes, but there're none, then it as well may be something
wrong, so let's not play smartass, but tell user outright what's
happening. But higher-level user in me knows that rebase is pretty
trusty nowadays, and real-world cause of empty commits during
rebase is that the change is already upstream. So, can we have
something like --skip-empty? Then some good time later, we can talk
about changing defaults ;-).
