Title: Cleanup utils

`Utils.new_files` is not used anymore.

`Utils.staged_files` is used in one place, with the same argument `"."` always. The staged files will always exist, so there's no need to check for existence (twice even). Instead of piping to `xargs` and splitting over `" "`, we can just split over `"\n"`.
