Let me know if you need any help.

OK, I have a stand alone patch that you don't need to fold in that does
this properly. I tested the crap out of it (missed a few places), but
should be good. I'll send that netx.

I have this working too, but want to test it a little more before
sending. Once I do, you can add both patches ahead of your series. I
may just apply them to my tree now and start running them through my
formal tests.
