While looking into clarifying the documentation of the side-effect-free
property, I noticed the safe-function property listed along with its
associated node in the manual, (info "(elisp) Function Safety").
This node makes no mention of the safe-function property or the related
user option safe-functions, both of which are documented in the
commentary of lisp/emacs-lisp/unsafep.el. That is, until one looks at
the Texinfo source, where this documentation was commented out quite a
So, my question is why was this documentation commented out? Is it
still relevant and welcome (probably following some copyedits), or
should it be deleted altogether?
