Merge lp:~jelmer/bzr-builddeb/merge-upstream-revision into lp:bzr-builddeb

[Jelmer Vernooij]

Fix the support for the -r argument to "bzr merge-upstream", when used without any arguments like --version.

In addition, allow merging upstream revisions that don't have a matching version in the primary upstream source.
