Re: [O] [PATCH] fix org-num-mode detect enabled already issue

[stardiviner]

Here is the screenshot which can demostrate this issue:

org-num-mode repeat after M-x org-mode.png
Description: PNG image

And here is the steps to reproduce this issue:

my config:

(require 'org-num)
(setq org-num-skip-footnotes t)
(add-hook 'org-mode-hook #'org-num-mode)

1. Then open an Org file, it has `org-num-mode` enabled because upper
   config added to hook.

2. Execute command with `[M-x org-mode]` again, then it will become as
   in screenshot.
