Well, ESS now "lives" @ github  (not my decision), and so the always
current source is there, in this case it is

     https://github.com/emacs-ess/ESS/blob/master/lisp/ess-r-mode.el#L264-L270

which is indeed defining `ess-r-mode-map` ... and I think I would
expect in general that your own elpa version will be close to current
whereas OS installation in /usr/share/.. would typically be slightly older.
OTOH, those should have been more tested against other parts of your emacs etc..
