I had in mind :set attribute of defcustom, see info "(elisp) Variable 
Definitions"
https://www.gnu.org/software/emacs/manual/html_node/elisp/Variable-Definitions.html#index-set_002c-defcustom-keyword

but I have realized that I am unsure it the function is called for local 
variables. The original idea was to execute something like code of 
`org-toggle-link-display'.

If I got it right, Ihor tried to fix it, but he had to revert the change 
intended to apply local variables earlier

In the particular case of `org-link-descriptive' some code should be 
executed *after* changing of its value.
