That's almost exactly what the current search does. (It tries to cope a
bit with broken mailers by being a bit more expansive and for, err,
everything that references anything, so to speak).

I wouldn't think the registry or the agent have any info that isn't also
obtained from the search? And since we never know if we have found
everything we have to do the search in any case...

This will respect the `nnir-ignored-newsgroups' variable. Is that
adequate? If not we can always add (yet) another variable.

No worries!
