No, as long as the key *exists* we've always moved on to the next one
if it didn't match. It's only when it doesn't exist at all that we
aborted.

And if the system doesn't know about those names, it'll never show up.
We're mapping *from* windows to *us*. So if the zones aren't in
windows at all, there is no way for windows to give us that name.
