For that I think it's better to only obey electric-indent-mode if
Emacs>24.3 rather than use the electric-indent-mode-has-been-called crutch.

Looks quite different since it checks (>
electric-indent-mode-has-been-called 1), but if you say it's the same,
then I'll remove electric-indent-mode-has-been-called and let you check
Emacs's version instead.
