[O] New exporter - publishing org files doesn't include :tangle

[Bernt Hansen]

Hi Nicolas,

James Yuan noticed that the .org file that is published with my document
(http://doc.norang.ca/org-mode.org does not contain :tangle on any of
the source blocks.

One of the uses of this document is to pull up the file and tangle it to
create an emacs configuration but this seems to be broken in 8.0.

I'm using 

--8<---------------cut here---------------start------------->8---
               :publishing-function (org-html-publish-to-html 
org-org-publish-to-org)
--8<---------------cut here---------------end--------------->8---

Regards,
Bernt
