Committing this, though this is not the same mechanism for completing
releases as used in _apt.

True. But I currently don't see the actual benefit in parsing
'apt-cache dump' instead of reading 'sources.list'. Are there any
regular uses that would justify such an expensive action?

Both

deb http://http.us.debian.org/debian/ stable main

and

deb http://http.us.debian.org/debian/ sarge main

will result in apt-cache dump producing
Archive: stable, and thus an offering of -t stable for completion.

I'm not sure if this makes it more or less suitable.
