Hrm, I'm pretty sure this can't work: Mapping.find("foo") will always be
successful as long as "foo" has an ordinary override (ie, the traditional
priority/section override) -- which it always will in Debian.
Swapping them around (so the Pkg/Arch test is first, followed by the Pkg
test only if that fails), should thus make the arch-specific overrides
work, at the cost of losing the original overrides for those packages.
My tests seem to bear this out.
So, that probably means:

needs to be changed. :-/
The easiest way I can see of doing it is having a second parse over
the overrides once they've been collated to add all the "foo" overrides
to all of the "foo/bar" overrides. Ugly though.

The other problem with this is that it uses the .deb arch, not the
Packages file arch -- so you get "all" instead of "i386", eg. Can probably
ignore that, but it'd be good to avoid.
