I am not sure about this: we already have this anomaly for output=files
say. Also I can imagine calling notmuch address --limit=1000 ... to get
a bunch of recent addresses quickly and I really am wanting to look at
1000 messages, not collect 1000 addresses.

Additionally, the 1000 message approach makes sense when we start
deduping whereas 1000 authors becomes unclear.

The exclude text needs updating as flag makes no sense for the address
command.
