Hey Ray,

Sorry it took awhile to get to this, I had my hands full with getting bug
379349 done before the 1.9 freeze.

No, you're right. :) The test needs to be fixed. Your code has a couple of
mistakes in it, though.

I'm guessing you meant .three and .four there.

The class and ID here are actually valid, because identifiers are allowed
to contain escaped anything. See the note at the end of section 4.1.3:
   http://www.w3.org/TR/CSS21/syndata.html#characters

I swapped the colors and changed the escape to represent '1' instead of
U+0001. (Hexadecimal digits can't be escaped with a backslash: they'd be
indistinguishable from Unicode escapes otherwise.)

Here's the diff. Check it. If it looks good to you, I'll check it in.
