It turns out IE is more screwed up than I thought. We can remove the bottom
margin quirk on the following elements:

   BLOCKQUOTE
   DL
   DIR
   FORM
   H1
   H2
   H3
   H4
   H5
   H6
   MENU
   OL
   UL

Incidentally, it turns out that IE6 doesn't actually do 1em margins on block
level elements, it does 19px margins. At least it does in my test case where 1em
= 16px. I don't want to know what it really is. Anyway, the net result is that
the test case should be considered passed in Mozilla if the green and yellow
bands in the left hand column are in the right order, rather than being exactly
aligned with the right hand column.

I give up. IE is too quirky. This bug should just be a matter of removing the
relevant lines from quirk.css, don't let this become some sort of project to
mimic IE in any way required to fully "pass" the test case.
