Sorry for repying to myself here, but I'm not convinced again. Or to
be more specific: I think this kind of refactoring is totally out of
the scope of this patch. So although I agree with you in priciple, if
you don't mind I'll keep the first two patches simpler and less
invasive. I'll look into the refactoring as a third step.
