It was always like this for patches that came through me. Greg's script
generates an explicit "From:" line in the patch, but I never saw the
value in that since git does the right thing by looking at the "From:"
line in the mail header.

The right thing is being done in stable-rc and for the releases. For
your example here, this is how it looks like in the stable-rc tree:
