Re: git-shortlog hangs on bare repo without --bare option

A few complexities I found were:

  - some things really want no setup, like init and clone. I don't
    recall the exact issues, but trying obvious things caused breakage
    there.

An obvious thing is to start these commands in a subdirectory of an
existing git worktree.

  - the setup needs to not just be part of git.c, but factored out so
    non-builtin C programs can use it.

Obviously.
