I'd be happy to help with the documentation, but I still don't
understand the behavior.  It seems as though some arguments
to :results need to be supplied to the code block, but others have to
be supplied to the call.  In my situation, the "org" option
to :results has to be supplied to the call, while the "output" option
has to be supplied to the code block.

What's the logic?

Here's my setup:

#+results: list1
- Item1
- Item2


#+results: list2
- Item3
- Item4

#+source: print_list(lst)
#+begin_src sh
  for i in $lst; do
    echo "* $i"
  done
#+end_src

Here's a way of calling that works
#+call: print_list[:results output](lst=list1) :results org

#+results: print_list[:results output](lst=list1)
#+BEGIN_ORG
* Item1
* Item2
#+END_ORG

but this way of calling doesn't
#+call: print_list[:results output org](lst=list2)

#+results: print_list[:results output org](lst=list2)
: * Item3
: * Item4

and neither does this way
#+call: print_list[:results org](lst=list2) :results output

#+results: print_list[:results org](lst=list2)

or this way
#+call: print_list(lst=list2) :results output org

#+results: print_list(lst=list2)
#+END_ORG
#+BEGIN_ORG

Thanks for any enlightenment!
