Hi All,
I hacked together a small workaround for the ungrouped undo-list entries
(undo works only characterwise in org-mode, but usually chunks together
several key strokes in, e.g., text-mode).
I have this piece of code in my emacs startup script.
-----–----------------------------->8-----------------------------------
;; implement undo grouping for org-mode
(setq org-self-insert-command-undo-counter 0)
(defadvice org-self-insert-command (after compact-undo-list () activate)
"Compact the undo list by removing some boundaries."
(if (not (eq last-command 'org-self-insert-command))
(setq org-self-insert-command-undo-counter 1)
(if (>= org-self-insert-command-undo-counter 20)
(setq org-self-insert-command-undo-counter 1)
(when (> org-self-insert-command-undo-counter 0)
(when buffer-undo-list
(when (not (cadr buffer-undo-list)) ; remove nil entry
(setcdr buffer-undo-list (cddr buffer-undo-list)))))
(incf org-self-insert-command-undo-counter))))
-----–----------------------------->8-----------------------------------
The advice post-processes the local buffer-undo-list and removes some
undo-boundaries. The behavior is modeled after emacs' command_loop.
Feedback welcome.
Cheers,
Martin

[resent, as the previous attempts didn't make it to the list ...]

Excellent, thank you very much.
I have installed this code (not using advice, but directly).
