Saying "div#car" is literally saying find me all "div" tags, where

out which one has an id of "car".
That's the way it worked pre 1.1. Now, it's "get #car and check if it's a
div".
I actually thought that was the case now, but it's still faster not to
perform additional checks if not needed.
Plus, what happens if you have:
<div id="bam" />
<span id="bam" />
What if you need to retrieve the span tag? If it's checking #bam first,
won't it only find the <div /> element?
It'll retrieve the first occurence only. The span is lost then...
