Yes, I did, starting with that range.  But I kept finding more patches that
seemed to need to preceed it ( cf88a3bcc442d70e10d3969e1edfc8430d74172f,
(40c9dcbfd026f0d0dd73dcf5a189ead7d1ba2d0f, 
48a18b3c698295e4d891f34e919615e84e20f027,
ad6d45fa0837acf3e8cab323ee5b08e05a9410a5).  Perhaps the original set should
have been easy to port to 1.0, and I just didn't know what I was doing,
but there seemed to constantly be more previous changes needed.
