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.
