I just tried applying the patches locally here. The patch looks the same way
for me, but 'git am' actually works while 'patch' does not.

Maybe Bjorn is using an outdated git version. While the patch clearly shouldn't
have been sent that way, I think git has been changed now to work around that.
I'm using a git-2.1 snapshot here.
