* lisp/ob-core.el (org-babel-execute-src-block): Post-process and
return results even when "none" results parameter is given. Document
that the result value is returned, as it is assumed by
`org-babel-ref-resolve'.
(org-babel-result-cond): Do return results even when "none" results
parameter is given.
According to the manual ":results none" should only affect how the
results of evaluation are inserted into the buffer. However, the
results are simply ignored currently. Fix this.
* lisp/ob-ref.el (org-babel-ref-resolve): Set :results to "none" when
resolving noweb references. Together with the above changes, this
makes Org not echo the results value yet returning the value
programatically.
