[PATCH 1/3] t/rebase: add failing tests for a peculiar revision

[Ramkumar Ramachandra <artagnon@gmail.com>]

The following commands fail, even if :/quuxery resolves to a perfectly
valid commit:

  $ git rebase :/quuxery
  $ git rebase -i :/quuxery

This is because rebase [-i] attempts to rev-parse ${REV}^0 to verify
that the given revision resolves to a commit.  Add tests to document
these failures.
