That's the case I'm concerned with. And I think the guessing confuses
users in many cases. It certainly has confused me.

It's a way of showing that human beings can't understand git's
guesswork. :-) It was also a (failed) attempt to understand the rules
of this heuristic. And an attempt to show the developers that the
rules have gotten out of hand.

Yes, I think the rules for the "short form" (the guessing when there's
no --) should be made simpler, or maybe the guessing should be dropped
altogether. I don't know. I don't know git well enough to be able to
be more specific. I just find the current behavior very confusing.

I don't know. It looks like it's not really addressing my specific
problem, because as far as I understand it only applies when there is
a --. But again, I don't know git well enough.

Anyway, thanks for your work. I'm sorry I can't provide more useful
input. This "short form" of checkout is just a small feature. I guess
I'm bikeshedding here.
