[ANN] Emacs-Guix 0.3.4

[Alex Kost]

Hello, Emacs-Guix (Emacs interface for GNU Guix) version 0.3.4 has been
released.  It may be installed with "guix package -i emacs-guix".

The main new features are:

1. "M-x guix-hash": it prompts for a file, calculates its hash and puts
   it into kill-ring (i.e., you can insert it with "C-y").  If it is
   called on a directory, it ignores VCS files (like "guix hash
   --recursive --exclude-vcs").  Also it supports dired-mode.  Thanks to
   ng0 for the idea of this command!

2. "M-x guix-derivation-mode": this major mode makes Guix derivations
   more human readable by indenting them and by making buttons from the
   store file names.  It is enabled automatically in "/gnu/store/….drv"
   files.  Many thanks to Oleg Pykhalov for inventing and implementing
   this feature!

3. As you probably know there are many single-line Guile files in the
   store, for example:

     /gnu/store/…-shepherd.conf
     /gnu/store/…-activate-service
     /var/guix/profiles/system/boot

   Similarly to the derivation files, the above files are not human
   readable as they are one-liners.  Now (I mean with Emacs-Guix 0.3.4),
   whenever you open such a file, it will be re-indented (its buffer,
   not the file itself!) and scheme-mode will be enabled there.

4. "M-x guix-superseded-packages": well, it just displays a list of
   superseded packages.

Happy Guix Year :-)
