Exactly, I was refering to *R* and there's no
problem in *.R buffers.

BTW: Just today, I've seen another bad example of fontification
     in a *.c file :
     A /* ......... */ region was 
     fontified as *string* - something I've never seen in earlier Emacsen.

  If you want to try: It's  starting at line 81 in
   https://svn.r-project.org/R-packages/trunk/Matrix/src/chm_common.c

Well, C-c C-r  and C-c C-c are a bit different,
but both end up going via ess-eval-region, so
your comment *is* relevant.

so you haven't seen good ole' Emacs 21.x for such a long time
that you  don't know anymore what you've left behind?
 :-) :-)
