Different incantation in .emacs:

(setq inferior-ess-r-help-command "help(\"%s\", help_type=\"html\")\n")

which works in both cases.

This is on OSX 10.8.2 (Mountain Lion), ESS 12.09-2, R 2.15.3 and Emacs 24.3. Albeit, I have had the same entry in .emacs for some years over numerous versions of R, Emacs, ESS and even OS's (Fedora Linux and OSX).
