I suppose it has to do with the following, wanted, behaviour:

+b abc* -->  server  <-- +b ab*

If the abc* reaches the server first, then the +b ab* needs
to send  -b abc* +b ab* to the _clients_ (not the server(s)
on the left, overlapping bans should be taken care of automatically).

Thus, apparently .12 fails to see if a ban coming in from
a server is already set exactly, in which case the whole ban
should be dropped/ignored.
