bug#2409: 23.0.90; org-mode + viper-mode + ns make typing unresponsive

[Andrew Hyatt]

I can't reproduce this under Emacs 25. As this bug is a bit old, I'm
guessing it has been fixed in the meantime. Please let me know if you
can still reproduce it, though. I'll mark this as unreproducible now,
and close it in a few weeks if you can't reproduce it either under Emacs
25.

Hi Andrew

I would like to give some feedback to what you originally asked Steve:

Did you check on OS X?

On GNU/Linux I never saw the issue, on OS X regularly under certain
circumstances which are not clear to me. With the recipe of Steve I
can reproduce on build GNU Emacs 25.1.50.1 (x86_64-apple-darwin13.4.0,
NS appkit-1265.21 Version 10.9.5 (Build 13F1507)) from
http://emacsformacosx.com/emacs-builds/Emacs-2016-01-11_01-40-53-eb0643c-universal.dmg

Seeing as you can reproduce, I'll consider this reproducible... but I
cannot reproduce it myself on OS X.

bug#2409: bug#2409: 23.0.90; org-mode + viper-mode + ns make typing unresponsive

[Michael Brand]

Hi all

I did some trials in lisp/org/org.el with
- Emacs on OS X built with configure --with-ns, 24.5 and today's
  master
- Org from today's master

1) Removing the line containing org-self-insert-command from

       (org-remap org-mode-map
                  'self-insert-command 'org-self-insert-command
                  'delete-char 'org-delete-char
                  'delete-backward-char 'org-delete-backward-char)

   lets the issue disappear. So the issue seems at least _related_ to
   org-self-insert-command.

2) When I instead remove all forms that contain
   org-self-insert-command or orgtbl-self-insert-command and then add

       ;; Reduce to a passing through to `self-insert-command'.
       (defun org-self-insert-command (N)
         (interactive "p")
         (self-insert-command N))
       ;; Leave this as it was originally.
       (org-remap org-mode-map
                  'self-insert-command 'org-self-insert-command
                  'delete-char 'org-delete-char
                  'delete-backward-char 'org-delete-backward-char)

   the issue remains but I expect it to disappear. Did I not replace
   self-insert-command just with itself and it should behave the same
   way as with change 1)?

bug#2409: Status: 23.0.90; org-mode + viper-mode + ns make typing unresponsive

The bug was considered by several people in this thread as
non-reproducible.  Although I am not entirely it is not reproducible,
I close it, considering it is quite old now.

Steven, feel free to report the bug to emacs-orgmode@gnu.org is it is
still there.
