[PATCH] gnu: Add emacs-ess.

[Roel Janssen]

Dear Guix,

I have a question about the following patch to add emacs-ess.
By default, the build files rely upon a LaTeX distribution to be
installed to generate a PDF from its Texinfo documentation.

I know that texlive is quite a heavy package, so should I separate the
output of this package in "out" and "doc", and substitute/patch the
involved Makefiles?

You can find the patch below.

Kind regards,
Roel Janssen
