Variable: org-fold-core-extend-changed-region-functions
org-fold-core-extend-changed-region-functions is a buffer-local
variable defined in org-fold-core.el.gz.
Documentation
Special hook run just before handling changes in buffer.
This is used to account changes outside folded regions that still affect the folded region visibility. For example, removing all stars at the beginning of a folded Org mode heading should trigger the folded text to be revealed. Each function is called with two arguments: beginning and the end of the changed region.
