commit a98ae424d2d4b5f11eeb1e2ef5699855d18887e5
Author: Ihor Radchenko <yantar92@gmail.com>
Commit: Ihor Radchenko <yantar92@gmail.com>
org-element-cache: Give user more control over silent modificatoin checks
* lisp/org-element.el (org-element--cache-silent-modification-check):
New variable allowing the user to suppress modification checks completely.
* lisp/org-element.el (org-element--cache-sync): Support
`org-element--cache-silent-modification-check'.
The existing heuristics for built-in non-modifying commands that
change `buffer-chars-modified-tick' is not sufficient. At least
`capitalize-word' changes the tick regardless whether the buffer was
actually modified or not. Yet, `capitalize-word' does not call
`after-change-functions' if the buffer is not really modified.
