Re: [Babel][Bug] Inconsistent output from babel function depending on how called

[Ethan Ligon <ligon@are.berkeley.edu>]

So, the ":result output org" ought to be associated with the *call*,
not with the function.  That makes good sense.  But perhaps it still
doesn't work quite as it ought...

If I do this, I get
#+results: print_list(lst=list1)
#+END_ORG
#+BEGIN_ORG

which is surprising first because there's no proper output, but also
because the end and begin tags are reversed (!).

What *does* work is to omit the "output" header argument.
#+call: print_list(lst=list1) :results org

#+results: print_list(lst=list1)
#+BEGIN_ORG
* foo
* bar
#+END_ORG

So now I definitely have a good work-around, but still think there's a
bug.

Thanks,
