IPv6 literal support in multisite broken

The logic for handling explicit port numbers in wp-includes/ms-settings.php is confused by IPv6 literal addresses in URLs as defined by RFC 2732.
It tries to handle the URL as it as if there were a port appended, but then fails to strip it off. Incidentally the error message here: 'Multisite only works without the port number in the URL.' is untrue, since ports are handled (but for only two particular cases, port 80 and 443).
The attached patch, against Wordpress 3.0.3, fixes both these issues, and allows ports other than 80 and 443 to be used with Wordpress, by just stripping off the trailing port rather than special-casing the two well-known ports, and not incorrectly detecting IPv6 literals as URLs with ports in. It also has the advantage of being much more compact.
It may be worth someone thinking through whether the substitution is strictly correct with reference to the URL standards, but I'm pretty sure that this is an improvement on the current code.
