>Description:
getnameinfo(3) supports these address families; it would be nice if this were reflected in the getnameinfo(1) utility.

Also might be nice if getnameinfo(1) supported the same `-f <family>' option as getaddrinfo(1) (and it might be reasonable for getaddrinfo(1) to support the common -4/-6 abbreviations for this).  Except getnameinfo(1) now uses `-f' for NI_NOFQDN.  Maybe that should be `-F' instead?

And it would be nice if getnameinfo(1) and getaddrinfo(1) agreed on how to spell the service/port number.  Currently this is not very symmetric:

$ getaddrinfo -f inet6 -p udp -s comsat localhost
dgram inet6 udp ::1 512
$ getnameinfo -u -p 512 ::1
localhost comsat
>How-To-Repeat:
mess around with getnameinfo(1) and see how much of getnameinfo(3) it can exercise
>Fix:
Yes, please!
