great. and in general, that should be the way - change your .emacs file
 rather than the ess files.

It should have worked - Martin requested R-devel so I hope he'll say
whether that works for him.

Did you have a byte compiled essd-r.elc file also in the dir?  in that
case, you either should have deleted the .elc file, or byte-compiled
again.

yes, those comments in ess-site.el (sec 1.4) look way out of date, and
are a candidate for removal - thanks for pointing that out.
