If anyone's depending on it, I'm sure it won't be too much trouble to
change.

I know a time when it could happen in the working copy: in a
directory, all entries have non-empty names except the dir itself --
because it cannot know its own name, it has the empty string for a
name. So if I were hashing entries for some reason, I'd probably want
that to Just Work.
