Additionally, replace one
(or (org-mode-p) (derived-mode-p 'org-mode))
with
(derived-mode-p 'org-mode)
cause that is reflexive anyway (returns true, if the current mode is
org-mode).
Delete one check testing for org-mode or org derived mode
Also remove blank lines before the ";;; org*el ends here" declarations.
Having a "Version" header forced us to update every file when releasing a
new version of Org; it also forced us to update every file when merging Org
with Emacs trunk, thus cluttering the diffs between the previously merged
version and the new one with useless information.
