[Orgmode] Making TAB a touch more magical

[John Wiegley]

In most "power" outliners on the Mac, pressing TAB indents the outline  
level of the current item.  This lets you add subnotes very quickly by  
typing M-RET TAB.  (I find M-S-<right> way too cumbersome to use while  
typing).

Since pressing TAB on a new entry (one with no body) doesn't do  
anything right now, I think TAB in that case should do what M-S- 
<right> does.  This little snippet achieves that:

(defun org-indent-empty-items (arg)
  (when (eq arg 'empty)
    (goto-char (line-end-position))
    (cond
     ((org-at-item-p) (org-indent-item 1))
     ((org-on-heading-p) (org-demote-subtree)))))

(add-hook 'org-pre-cycle-hook 'org-indent-empty-items)

This also works for regular lists.
