I just heard from someone on the ESS mailing list who suggested putting
the following in .emacs

;;Use this for ESS if using GNU Emacs 21

(if (string-match "GNU Emacs 21" (emacs-version))
    (add-hook 'inferior-ess-mode-hook 'my-inf-ess-hook))

(defun my-inf-ess-hook ()
  "Use regexps rather than field boundarys for movement in inferior
buffers. Only needed for GNU Emacs 21."
  (set (make-local-variable
'comint-use-prompt-regexp-instead-of-fields) t))

This works for me, though I don't have any idea what it is doing.
