[ESS] ANSI escape sequences in ESS

[Martin Maechler]

Interestingly, this *works* extremely nicely for me,  using emacs
23.4.1 (still the default on ubuntu 14.03 LTS).
I attach an emacs window screen shot, which at least Vitalie and Tamas will get.

(R 3.2.0 patched, "current";  emacs 15.09-devel "current")
