Current Behavior

When running the following command on a clean NixOS 22.11 install:

$ nix-shell "https://github.com/divnix/digga/archive/main.tar.gz" \
  --run "nix flake init -t github:divnix/digga"
error: getting status of '/nix/store/hh5r5spax8d8d0fbn8hvhixy4w8j8027-source/devShell.nix': No such file or directory

Steps to Reproduce

We should probably have tests for the compat files. For now, nix --experimental-features 'nix-command flakes' flake init -t github:divnix/digga should have the intended effect. In fact, this command should probably be what is recommended in the docs anyway since it is easier to remember and type, more obvious in its effect, and teaches a little about how to use nix-command. If we take that approach, I think the compat files would be unnecessary which saves us on complexity and testing.
