Automatically indent text when return is hit in an org buffer.

[Daniel Pittman <daniel@rimspace.net>]

G'day.  I am a fan of `newline-and-indent', and turn it on for most of
the modes I routinely use, since it is almost always what I want done.

org-mode rebinds the "return" key to `org-return', which acts
intelligently in the face of tables -- and calls `newline' hard-coded in
other cases.

I would like to preserve that intelligence, but also to use
`newline-and-indent', so generated this patch to implement my desired
behaviour.

By default this changes nothing: org behaves exactly the same way as it
did previously.


If this isn't the right approach I am happy to rework the patch to
better match the rest of the software.


Finally, while I believe that this is a trivial change and will not need
assignment papers anyway I can note two things:

 * there are copyright assignments from me to the FSF on record already
   for Emacs and constituents, so I don't know if I need a new
   assignment.

 * I am happy to disclaim this if necessary.

Regards,
        Daniel
