[NNTP] Command to list wanted groups for transit peers

Hi,

So, most (at least non-binary) peering arrangements include a list of=20
groups the server wants to accept.  Usually this is configured by hand,=20
but there are automated out-of-band methods to do it automatically (e.g.=20
GUP, the Group Update Protocol).

I think a better way to do it would be a new command, which would list=20
the groups the server wants to accept as a wildmat.  For instance:

S: 200 Server ready.
C: CAPABILITIES
S: 101 Capabilities list follows.
S: WANTGROUPS
S: ...
S: .
C: WANTGROUPS
S: 2xx List of groups follows.
S: *
S: @alt.sex.*
S: @*.bina*
S: de.bina*
S: !uk.test
S: .
C: CHECK <...

This would be an "extended" wildmat like INN uses; I don't think @ is=20
available in the RFC 3977 wildmats.

Thoughts?

Regards,
--=20
