Tested. Yes, it does!

Well, for this case, a host without domain would be just a host in
which there is not a FQDN in /etc/hosts for the hostname, for example:

192.168.1.3 myhost

If you can modify /etc/hosts in your own computer, you should be able
in theory to reproduce the failure.

Note: If you try plain dpkg-buildpackage to reproduce the error (as I
did right now to test the patch), you have to temporarily rename your
$HOME/.gitconfig file (where you will probably have another email
setting for git).

Thanks a lot.
