I didn't work out what the algorithms for the other browsers were, because 
IE's was actually sane for once (shockingly).

However, in Gecko, for instance, the following tests act differently than 
in IE:

   http://www.hixie.ch/tests/adhoc/dom/level0/history/002.html
   http://www.hixie.ch/tests/adhoc/dom/level0/history/003.html
   http://www.hixie.ch/tests/adhoc/dom/level0/history/004.html

Off-hand I can't really work out what Gecko is doing.
