Yup. I think you stumbled on a "bug" (though probably just more of an
oversight). I looked around a bit for the default babel header arguments
and think this looks accurate:
-
http://orgmode.org/manual/System_002dwide-header-arguments.html#System_002dwide-header-arguments

This, with nothing set for `:exports something`, the default is `:exports
code`.

What you did instead is correct -- you want to export results. I get the
same behavior: code only with no value set, results with `:exports results`
added. To "patch," that page, you would follow the procedure for
contributing to Worg:
- http://orgmode.org/worg/worg-git.html

You submit a key to Bastien, clone Worg, edit the file, and push your
changes.


Best regards,
John
