This breaks anything with a legitimate need to use URLs. If the nature
of the form is such that there's no legitimate need to post a URL,
that's one thing, but the strength of URL syntax is what the U stands
for: uniform.

That, and I wouldn't be surprised if spammers start using gopher:// URLs
instead, just to get around this.
