rebase: improve error message for empty --rev set

Before, it just said 'nothing to rebase' in this case. Now, it aborts
mentioning the reason: 'empty "rev" revision set'.

Specifying revisions that cannot be rebased is a 'soft' error, but specifying
an empty set deserves an abort that explains exactly what the problem is.
