Subject: org-link-expand-abbrev: Do not evaluate arbitrary unsafe Elisp code
* lisp/org/ol.el (org-link-expand-abbrev): Refuse expanding %(...) link
abbrevs that specify unsafe function. Instead, display a warning, and
do not expand the abbrev. Clear all the text properties from the
returned link, to avoid any potential vulnerabilities caused by
properties that may contain arbitrary Elisp.
