Interesting.   What happens in IE8b1 if you do:

   document.querySelector("")

?

You mean document.querySelector(undefined) matches <undefined> nodes, 
right?  That would be consistent with a JS Object.prototype.toString() 
happening on the argument, I guess.  It's not clear to me how 
"undefined" should behave with the "NoNull" decoration, for what it's worth.
