Hello Guix!

This adds emacs-ws-butler, which is handy to keep whitespace characters in
check!

To enable it, you can put the following in your .emacs:

--8<---------------cut here---------------start------------->8---
;;; Automatically trim whitespace
(add-hook 'prog-mode-hook #'ws-butler-mode)
--8<---------------cut here---------------end--------------->8---

Thank you,

Maxim
