[PATCH] ~org-font-lock-add-priority-faces~: ensure priority cookies are in a headline

["Sébastien Miquel" <sebastien.miquel@posteo.eu>]

[-- Attachment #1: Type: text/plain, Size: 273 bytes --]

Priority cookies are always in a headline.

The attached patch speeds up fontification of a 1k lines buffer by 0.1
second.

Note that the variable org-priority-regexp can't be modified since
it is used in the agenda and in org-get-priority.

Regards,
