[erlang-bugs] "erl -name app" fails if hostname doesn't contain a dot

Thank you Bengt. I think it should allow "localhost". Not every computer is
a server in a registered domain name, and in such situations, I don't think
having no domain name is so uncommon. I'm using a Ubuntu-based distro and
it didn't require setting a domain during installation, so I think it's
likely that many people will have the same issue. I didn't have any issue
with any other piece of software.
Also, like I said, there is a misleading contradiction. If you decide that
a FQDN is required, then "erl -name " should fail.

"hostname -f" should display the the FQDN (Fully Qualified Domain Name).
A FQDN consists of a short host name and the DNS domain name. I think
that only "localhost" is not correct.
