We only allow cuts at commits, not arbitrary objects. upload-pack will
fail eventually in register_shallow if a non-commit is given with a
generic error "Object %s is a %s, not a commit". Check it early and
give a more accurate error.
This should never show up in an ordinary session. It's for buggy
clients, or when the user manually edits .git/shallow.

Thanks. I agree with you that while this is not wrong per-se, this
will not matter in real life.
