Yes, I was thinking mostly of "X..Y" types of ranges, which are probably
the most common. I hadn't considered shallow repositories, and you can
also hit the root commit as a boundary if you do not specify --root.

I guess the question still in my mind is: what use does the identity of
the boundary commit have? That is, whether you know ahead of time where
the boundary is or not, is there ever a case where knowing its author
and/or commit sha1 is a useful piece of information, as opposed to
knowing that we hit a boundary at all?

I could not think of one, but I may simply lack imagination.
