No, it doesn't. > .txt are not > in .gitignore so annoying to use for patches. You don't have to create the file inside the Git repo, e.g. I dump patches to /tmp/patch.txt

Clearly all maintained branches. > I don't think it's actually a problem, since it's a trivial destructor anyway. Yes, me neither, I was only thinking about sanity checker tools when doing this so no plan for backports.
