This is what I imagine multi worktree support (aka git-new-workdir) looks like. Basically two variables will control access to the repo: $GIT_SUPER_DIR for worktree specific stuff and $GIT_DIR for the rest.
I like the idea of using git_path() to hide path relocation caused by GIT_SUPER_DIR, but I may have made some design mistakes here.. setup_git_directory() changes are hairy. It's not surprise if I broke something in there. Not important for a PoC though. Final series may be a few patches longer as I only lay the foundation in this series.
