Ugh.  I'm an idiot.  I implemented this change in WebKit and even brought it
up on list.  :-)  Thanks for pointing it out.

It's already changed in WebKit, so I suspect the next version of Safari will
be fixed.  Similarly, the next stable version of Chrome (which is about to

Anyway, I already have a patch out to change from uri -> url.  Sounds like
