+`host` supports wildcards (`*`) for pattern matching. `<host.tld>` takes
+precedence over `<host.*>`.

 `port` will always be `nil` except when the remote URI configured locally is
 http(s) **and specifies a port** (e.g. `http://localhost:3000/user/repo.git`),
 in which case the generated url permalink also needs the right port.
