[PATCH 2/2] emacs: Add shell completions for "guix" command.

[Alex Kost]

Oof!  There is a plenty of guix commands, actions, options, …
So after this patch, it would be more convenient to use ‘guix’ in
"M-x shell".

It should complete almost everything except suboptions of subcommands, I
mean those ‘import’ modules (e.g., it will not complete
‘--no-test-dependencies’ option for ‘guix import hackage’ command).

Completing may lag a bit from time to time.  It happens because shell
commands (like ‘guix ... --help’) are called when necessary to find
options, packages, etc.  But the found entries are "memoized" so next
time the same entries will be completed much faster.

Many thanks to Ludovic for the great idea of this package!
