Yes, I think we can agree that between APT and dpkg, we ought to
arch-qualify all M-A: same packages. But the fact is that the squeeze
version of APT doesn't do this and that squeeze's APT with
wheezy's dpkg should still work together.
And because of this dpkg must accept "dpkg -r foo" even if foo is M-A:
same. Failing is not an option and foo:* is not really what APT meant
internally.
