More fixes of Intro to Emacs Lisp
* doc/lispintro/emacs-lisp-intro.texi (Finding More): Tell the
reader how to invoke 'M-.' without a tags table. Add a
cross-reference to the Emacs manual for when a tags table does
need to be created.
(append save-excursion): Rephrase a confusing sentence.
(Bug#31578)
