[O] Babel: RESULTS for no value

[Jarmo Hurri]

Greetings.

Would it be feasible to change Babel so that it would *not* output
#+RESULTS: into the org buffer in case there is absolutely no value for
a block?  Consider the following example, which draws an Asymptote
picture in an external viewer.

# ------------------------------------------------------------------
#+BEGIN_SRC asymptote 
size (5cm);
filldraw (unitcircle, red);
#+END_SRC

#+RESULTS:
# ------------------------------------------------------------------

The #+RESULTS: line is produced even though there is no output from the
block.

Making this change would make my life a bit simpler in finalising
Processing support for Babel.
