By `trying harder' I mean that it should recognize
`localhost.localdomain' as a very improbable FQDN and try to ask the
name server, instead.

It used to be that Emacs used the output of the `domainname' command
(well, the appropriate equivalent library function or system call),
but that was the NIS domain and not the DNS domain...

My idea is that Emacs should look if there is /etc/resolv.conf and if
there is a nameserver entry in it, and if so, it should ask the name
server for the FQDN of the local host.  (Unless the FQDN was found
already in /etc/hosts.)
