you're right. it wasn't a very hard change, provided you knew where to make it,
which I didn't at first.
After a little hunting, r2285 in svn trunk implements raw rank as RankScheme 2.
Check out svn trunk and post back here to let us know if it works for you or
not. I still haven't made the 2.4.7 release, so it can be in there if I hear
positive feedback about it in the next few days.
