This is the one git was complaining about on your end? b4 gets it for me viab4 shazam https://inbox.sourceware.org/gcc-patches/dbtiy6uch8xb.3522x0caqi...@gmail.com/it's a little mangled: the "Hi," is in there, and there's two different line-breaking lengths. So maybe something's odd with the patch, b4 is pretty good about just making stuff apply when it's been a bit mangled.
I normally use git-format-patch, paste this into my mail client and sometimes add some lines but that's about it. It used to work before so I'm hoping there's nothing fundamentally broken in my work flow?
Some months ago I started using format=flowed by default maybe that causes different line-breaking lengths?
