raw org and drawer imply verbatim results

  This unifies the results handling across a number of different
  languages.  It is still possible to force tabular output by adding the
  ":results table" argument.

The following example demonstrates the results in shell python and perl.

** drawer and table
#+begin_src sh :results drawer table
 echo -e "1\n2\n3"
#+end_src

#+RESULTS:
:RESULTS:
| 1 |
| 2 |
| 3 |
:END:

#+begin_src perl :results drawer table
"1\n2\n3"
#+end_src

#+RESULTS:
:RESULTS:
| 1 |

:END:

#+begin_src python :results drawer table
return "1\n2\n3"
#+end_src

:END:

* lisp/ob-core.el (org-babel-result-cond): The "raw", "org" and "drawer"
  :results header argument values preclude table processing unless the
  "table" argument is given as well.
