you know that thing in emacs where up to 20 self-insert-command
invocations are undone all at once? i dislike it and have fixed it
for everything except one command in org.
in org, backspace [org delete backward char] clusters for undo
["amalgamates" in emacs lingo] even when
org-self-insert-cluster-for-undo is nil. this is not true of delete,
which works ok.
here is my code to try to fix it [note that i fix teh rest of emacs 25
also]. but that one command does not accept the undo-boundary that i
call. i do not udnerstand why this is the case.
(defun alpha-wrap-with-undo-boundary (old)
(interactive)
;; (defun (make-symbol (concat "alpha-") old) ()
;; (interactive)
(call-interactively old)
(undo-boundary))
(define-key global-map [remap delete-char] #'alpha-delete-char)
(define-key global-map [remap delete-forward-char]
#'alpha-delete-forward-char)
(define-key global-map [remap delete-backward-char]
#'alpha-delete-backward-char)
(define-key global-map [remap backward-delete-char-untabify]
#'alpha-backward-delete-char-untabify)
(defun alpha-delete-char () (interactive)
(alpha-wrap-with-undo-boundary 'delete-char))
(defun alpha-backward-delete-char-untabify ()
(interactive)
(alpha-wrap-with-undo-boundary 'backward-delete-char-untabify))
(defun alpha-delete-forward-char ()
(interactive)
(alpha-wrap-with-undo-boundary 'delete-forward-char))
(defun alpha-delete-backward-char ()
(interactive)
(alpha-wrap-with-undo-boundary 'delete-backward-char))
;; ;; not work. it is an alias. trying org versions.
;; (define-key global-map [remap backward-delete-char]
#'alpha-backward-delete-char)
;; (defun alpha-backward-delete-char ()
;; (interactive)
;; (alpha-wrap-with-undo-boundary 'backward-delete-char))
(define-key org-mode-map [remap org-delete-backward-char]
#'alpha-org-delete-backward-char)
(define-key org-mode-map [remap org-delete-char] #'alpha-org-delete-char)
(defun alpha-org-delete-char () (interactive)
(alpha-wrap-with-undo-boundary 'org-delete-char))
(defun alpha-org-delete-backward-char () (interactive)
(alpha-wrap-with-undo-boundary 'org-delete-backward-char))

Without looking at this too closely, I'd guess it's because ...

... you're trying to remap a command that is itself remapping a command.
(info "(elisp)remapping commands")
In addition, remapping only works through a single level; in the
following example,
(define-key my-mode-map [remap kill-line] 'my-kill-line)
(define-key my-mode-map [remap my-kill-line] 'my-other-kill-line)
‘kill-line’ is _not_ remapped to ‘my-other-kill-line’. Instead, if
an ordinary key binding specifies ‘kill-line’, it is remapped to
‘my-kill-line’; if an ordinary binding specifies ‘my-kill-line’, it
is remapped to ‘my-other-kill-line’.
Perhaps just bind it directly?

ah, so org did the remap and i tried to remap the remap?
my brain is not working right now, but i think you might be right. in
either case, your solution works and is straightforward.
thank you.

Yes, with the standard value for org-mode-map, here's what
describe-variable (C-h v) says:
(remap keymap
...
(delete-backward-char . org-delete-backward-char)
