[O] Scheme output results

[Neil Jerram]

I don't think that Scheme output results are correctly handled. Please 
consider:

#+BEGIN_SRC scheme :results output
(display "a") (newline)
(display "b") (newline)
(display "c") (newline)
'(a b c)
#+END_SRC

#+RESULTS:
: "a\nb\nc\n"

As compared with the Elisp equivalent:

#+BEGIN_SRC elisp :results output
(princ "a") (terpri)
(princ "b") (terpri)
(princ "c") (terpri)
'(a b c)
#+END_SRC

#+RESULTS:
: a
: b
: c

I have a possible fix for this - on another computer, so not to hand 
right now - but thought it would be check first whether you agree with 
me that the Scheme results should be more like the Elisp ones.
