Hi Guix,

I noticed that unless geiser-guile-load-path is given an absolute path,
emacs-guix doesn't work properly.

Here's a recipe to see it failing:

Write a file, say test-emacs.el:

--8<---------------cut here---------------start------------->8---
(with-eval-after-load 'geiser-guile
  (add-to-list 'geiser-guile-load-path "~/src/guix"))
--8<---------------cut here---------------end--------------->8---

$ emacs -q -l /path/to/test-emacs.el

M-x guix p n

--8<---------------cut here---------------start------------->8---
Starting Guix REPL ... [5 times]
guix-geiser-eval: Error in evaluating guile expression: ice-9/boot-9.scm:1685:16: In procedure raise-exception:
error: package-names*: unbound variable

Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
scheme@(emacs-guix) [1]>
--8<---------------cut here---------------end--------------->8---

The attached patch fixes the code snippet in the documentation, thus
preventing others from stumbling on it.

Thank you.
