org.el (org-fontify-extend-region): Fix headline fontification in edge case
* lisp/org.el (org-fontify-extend-region): Fix fontification of headline or meta line created by inserting a newline. Unrelated to the fix: `org-fontify-extend-region' is added to `font-lock-extend-after-change-region-function' and doesn't need to use `save-excursion'.
