rebase -i: we allow extra spaces after fixup!/squash!

This new test case ensures that we handle commit messages that start
with fixup! or squash! followed by more than one space. While we do
not generate such messages when committing with --fixup/--squash, it
is perfectly legal for users to hand-craft their own fixup messages,
and we heed Postel's law by being lenient.
