[PATCH 1/6] t/checkout-last: checkout - doesn't work after rebase

[Ramkumar Ramachandra <artagnon@gmail.com>]

The following command

  $ git checkout -

does not work as expected after a rebase.  Every kind of rebase must
behave in the exactly same way: for the purposes of checkout -, the
rebase event should be inconsequential.

Add two failing tests documenting this bug: one for a normal rebase, and
another for an interactive rebase.
