Clarify add-to-list documentation (bug#39373)
While add-to-list often works with lexical variables, this is a hack that isn't always effective; better tell the user not to try. * doc/lispref/lists.texi (List Variables): Add a note about lexical variables to the add-to-list description. Fix the equivalent code. * lisp/subr.el (add-to-list): Amend doc string.
