I've just pushed a patch to britney which automatically removes obsolete
source packages from testing.  These will still be in unstable
(otherwise they'd have been removed via that route in any case) and
won't have explicit hints, so will cause trille to fall back to the
generic "(no removal hint found)" message.

It would be handy if these could somehow be labelled as automated
obsolete package removals in the notifications.  I can't find an obvious
way of doing that right now though.

Or fall back to finding a completely irrelevant hint ;)
But it already did that.

Cheers,
Julien
