gnu: Add emacs-rainbow-delimiters

  Dear Guix,

Here's a trivial patch to add rainbow-identifiers that even makes bad
code look pretty ;).

Is it OK to push?

Kind regards,
Roel Janssen

I think it's OK, except...

... this line should be written like this:

                 (file-name (string-append "rainbow-identifiers-" version ".el"))

Otherwise (with your variant) the final elisp file would have
"emacs-rainbow-identifiers.el" name, which is not correct: it should be
named "rainbow-identifiers.el" because it provides 'rainbow-identifiers'
feature.

If I read it correctly, this is FreeBSD license (i.e., 'license:bsd-2'):

Right.  Thank you for this catch!  It still generated
rainbow-identifiers-autoloads.el, which I guess is why it loaded just
fine in my Emacs.  For future Emacs packages, I will add this to my list
of things to verify as well.

You're absolutely right.  I think I now know why the other one is called the
"3-clause" :).

I pushed it with these changes.
Thanks for your quick response!
