#+OPTIONS: ^:nil affects to buffer sub-superscript visualization

[General discussions about Org-mode.]

Hi

Having this text in the body of a headline, makes that superscript and 
subscript visualization doesn't work in that buffer:

#+OPTIONS: ^:nil

I suppose that should affect just to exportation, not to buffer 
visualization.


Tested in emacs-q.

Example of buffer, it can see using these 2 commands 
(org-toggle-pretty-entities), (org-mode-restart) and adding or killing a 
";" before #+OPTIONS:
