          **fall — Fetch ALL**

          *fall* runs `git fetch` and `git status` over every repository path
          listed in `~/.config/fall/repos.conf`, using parallel jobs for speed.
          With `fall .`, it can instead work from a project-local `.repos.conf`
          discovered by walking up the directory tree.
