#+PROPERTY: results output code append

See the aforementioned sec. 7.1 of the manual. Equivalently,

* foo
  :PROPERTIES:
  :results: output code append
  :END:

That's a consequence of the property syntax. On the code block
header line however, you have to have some purely syntactic
marker to distinguish properties from their values, hence

#+begin_src foo :results output code append :exports both
...

The trick is to think of the colon as a delimited (like a comma)
not as a part of the property name.
