I have just noticed that this (currently topmost) commit lists my name as the author. That was not my intention. Norihiro Tanaka should be listed as the author. I plan to take the unusual step of replacing that public/pushed commit with an identical one with that important correction. Then I will post instructions telling people how to deal with this unusual situation.
Norihiro, you can help avoid recurrence by submitting future patches created by running "git format-patch --stdout -1". That way, your name is recorded in the patch, and I don't have to take extra steps to add it when creating a commit.
