Hello,

 I'm resending the patch yet again. See below. I missed that
'(revision "0")' and didn't run `guix lint`. (Sorry, I'm learning)

> You also need to add `cscope' as an input, and patch "xscope.el" so
> `cscope-program' point to the proper binary, using
> `emacs-substitute-variables'. See, e.g., emacs-plz package for an
> example.

`guix style` makes this line too long. I guess I can ignore that, right?

Regards
Bost
