 Let’s say you have a git repository `S` inside another git repository `M` (for instance because of [#5](https://github.com/cljoly/telescope-repo.nvim/issues/5)), but `S` is in a directory that’s ignored in the `.gitignore` in `M`. `S` wouldn’t appear in the Telescope list of this extension by default, because it is ignored (`.gitignore` are taken into account by default).
