I should have searched the group archives first. I found a
satisfactory solution from a 2002 posting :)

(defun bja-open-line-below ()
  (interactive)
  (end-of-line)
  (open-line 1)
  (next-line 1)
  (indent-according-to-mode))

(defun bja-open-line-above ()
  (interactive)
  (beginning-of-line)
  (open-line 1)
  (indent-according-to-mode))

(global-set-key [?\C-o] 'bja-open-line-below)
(global-set-key [?\M-o] 'bja-open-line-above)

Being able to customize emacs with elisp is one of the main reasons
I'm considering a switch (that and being able to use emacs/slime for
Lisp programming).
