Would it perhaps make sense to do something like Roman's patch for 4.9
and then consider further changes down the road?  Roman's patch
appears to fix a real bug, and I think that, while not really ideal,
the code is an incredible mess right now and Roman's patch (assuming
it's correct) makes it considerably nicer.
