indenting is weird.  what is baseUrl?  Can we pass KURL for the url?  scheme is
a subset of ASCII, right?  Maybe we can pass a WebCString instead.

baseURL is the baseURI of the document of the page that RPH is called on -
actually there's a bug here because the url argument here is a relative URL
fragment.

I'll join baseUrl together with url into a GURL and pass that around (unifying
the relative and absolute url paths for registerProtocolHandler), and I'll use a
WebCString for url, too.
