This agrees with my testing. And from script (not fully relevant to  
the protocol, but perhaps of interest), document.cookie="foo" creates  
a cookie named "foo" with an empty value, rather than a nameless  
cookie, while document.cookie="" does nothing, so we would have been  
hit by the Mozilla bankofamerica bug cited earlier.
