No, because the problem is that the short name always resolves to
the IP the machine would have in the local network, and hence this
is the IP that OpenSSH tries.

However, if the machine is not in the local network, then I'd like
OpenSSH to ask for the same hostname in the next CanonicalDomain and
try it there. Does this make sense?
