I think "many more years".

Since I very often work from home via "emacs -nw", I've known
liked font-locking of my xterm / gnome-terminal for a long time.
It has worked with S / R ``always''.

I've checked and tested a new version of <ess>/lisp/essl-sas.el
where I've just dropped the "window-system" test,
and indeed, it did fontify *.sas files automagically.  Hence
this will be in ESS-5.2.12

(and is available from https://svn.r-project.org/ESS/trunk/lisp/ )
