Ah, no, that's not right either.  Pick the interface that puts the
division of abstraction at the right point.

The overview database is a database indexed by group and article number.
The interface should therefore be:

    OVadd(struct overview *, const char *group, ARTNUM article,
          struct overdata *)

so that the key is passed in explicitly.  That means that innd will have
to loop on the groups, but it doesn't have to build up a complex data
structure to store that information.  I expect that innd will want to end
up with a list of newsgroups anyway to do various other things, so it just
has to store the article numbers in that list as it assigns them.
