[ANN] Emacs-Guix 0.3.1

[Alex Kost]

Hello, Emacs-Guix (Emacs interface for GNU Guix) has been updated to
version 0.3.1.  It can be installed with:

  guix package -i emacs-guix

This release was done mostly to be consistent with some recent changes
in Guix (introduced since Guix 0.12.0 release), i.e. to keep "M-x guix"
keys up-to-date and to add some 'guix' completions for "M-x shell".

There are only 2 new commands:

1. "M-x guix-info": it opens Emacs-Guix info manual (with C-u, it opens
   the Guix manual).  Thanks to George Clemmer (aka myglc2) for
   suggesting this command.

2. "M-x guix-services-from-system-config-file": well, this command is
   rather useless at the current state, as it just shows a list of
   services (for a specified "config.scm") and nothing more.

BTW, if you don't like to read "info", Emacs-Guix manual is available
online now:

Many thanks to George for the huge help with this task!
