Yeah, it's unfortunately quite difficult to implement address matching
in ~/.ssh/config because of the interplay of Host matching, Hostname
directives, hostname canonicalisation*, proxy commands, hosts having
multiple addresses, IPv4/IPv6 and when the addresses are actually
resolved and available to the parser.

I've not figured out a clean way to do it that isn't also complex and
probably fragile to implement.
