Attached is a new version of the patch that will respect the variables
that also govern `org-insert-headline'. It's smarter and preserves the
layout better.
E.g. (where | is the cursor)
#+CAP|TION: foo
After M-RET it becomes
#+CAPTION: foo
#+CAPTION: |
A keyword-line is inserted above when one press M-RET between BOL and "#".
Keywords that an element can only have one of will not be inserted.
E.g.
#+NAME: foo|
After M-RET it becomes
#+NAME: foo
* |
Any opinions?
