More complete test...

* Test 1 -- OK!

** Anonym block

#+begin_src emacs-lisp :results output org
(print "Test")
#+end_src

#+results:
#+BEGIN_ORG

"Test"
#+END_ORG

** Named block

#+source: echo
#+begin_src emacs-lisp :var n="me"
  (message "hi %s" n)
#+end_src

#+results: echo
: hi me

* Test 2 -- OK!

Setting a global data through a fake results block:

#+results: max-lines
: 200

Then using it:

#+source: print-max-lines
#+begin_src emacs-lisp :var n=max-lines
  (message "there are %s lines" n)
#+end_src

#+results: print-max-lines
: there are 200 lines

The latter results block is deleted. The former, with the assignation, is not.
Excellent!

* Test 3 -- Not OK... <<<

And the call line for the named block:

#+call: echo()

#+results: echo()
: hi me

This results block is not deleted, while it should?
