I didn't pay close attention to the lftp bug reports, so what I'm saying 
may be nonsense.  But wouldn't it make more sense to just remove 4.8.0-1 
if it's broken?  You could still make 4.7.8-1 a test version, leaving a 
working 4.7.7-1 as current.

Doing it this way, you wouldn't need anything but the ability to mark a 
release as "test".
