[ESS] [ESS-bugs] ess-mode 5.9.1; autocompletion of file path always uses initial working directory

And just in case anyone is wondering 'why M-RET'?..

It is because XEmacs has had a similar facility in *shell* buffers bound
to that same key: shell-resync-dirs.

Emacs currently has a function called 'M-x dirs' which does the same
thing.  So you for Emacs users you can do:

(add-hook 'shell-mode-hook 'my-shell-hook)
(defun my-shell-hook ()
  " my hook to change local shell-mode-map."
  (define-key shell-mode-map (kbd "M-RET") 'dirs))

I'll get in touch with Emacs developers to see if this could be added to
Emacs, but in the meantime, the above should work.
