Hey, look, it's another one... This prevents the wiki formatter from adding the base URL to URLs starting with //.
// is a rather obscure but incredibly handy feature of URLs that a lot of people don't know about. It's an *absolute* URL using the same schema as the currently loaded page. For example: //cowlark.com/binary.png This is primarily useful when dealing with pages that use https. Most modern browsers will refuse to load content via http on an https page, so if I were to link to http://cowlark.com/binary.com from https://cowlark.com/calculon, all I'd get is a broken link. Using a // URL ensures that it's loaded by either http: or https: depending on what's appropriate for the page. Patch enclosed.
