The good news is that C-c RET (bound to comint-insert-input) in
*shell* buffers now works again in today's CVS Emacs.  The bad news is
that C-c RET still does not work in *R* buffers in CVS.

I _think_ this is because comint-insert-input relies on fields to be
defined in *R* buffers and we have
comint-use-prompt-regexp-instead-of-fields set to t, which is needed
for other parts of ESS (this changed a few years ago).

C-c RET  in Emacs 21.3 works, simply because that is bound to
comint-copy-old-input, which uses regexps.

This is something for a rainy day ...!
