[PATCH 0/9] remove dead shell code

Remove dead shell code in git-sh-setup, inspired by parallel discussion on another topic (but the two don't conflict): https://lore.kernel.org/git/87lf4f9gre.fsf@evledraar.gmail.com/

The last two patches were picked from a dropped series of mine submitted earlier this year, it was dropped because of other more complex patches that I haven't included here: https://lore.kernel.org/git/20210311001447.28254-1-avarab@gmail.com/
