* Avoid extending the directory without globs in `nu_engine::glob_from` * avoid joining a `*` to the directory without globs * remove checks on directory permission and whether it is empty The previous implemention of `nu_engine::glob_from` will extend the given directory even if it containes no glob pattern. This commit overcomes lack of consistency with the function `nu_glob::glob`. * Add flag -D to ls, to list the directory itself instead of its contents * add --directory (-d) flag to ls * correct the difference between the given path and the cwd * set default path to `.` instead of `./*` when --directory (-d) flag is true * add comments * add an example * add tests * fmt
