[O] [BUG] src code block header does not override buffer-wide header in property

[Nick Dokos]

This was reported on SO:

http://stackoverflow.com/questions/37414837/org-mode-overwriting-globals-properties-in-block-headers

The ECM is as follows:

--8<---------------cut here---------------start------------->8---
#+PROPERTY: header-args :results silent

#+BEGIN_SRC elisp
;; this one is silent
(setq foo "bar)
#+END_SRC

#+BEGIN_SRC elisp :results output
;; this one is being outputted
(princ "foo")
#+END_SRC
--8<---------------cut here---------------end--------------->8---

The second code block *should* output "foo" as its result, but it does
not: the :results silent header in the property seems to be in conrol.

Org version: Org-mode version 8.3.4 (release_8.3.4-1026-gf0ff25 @
