These changes are the combination of the commits below (in order applied). Unlike other backports, these are applied in one commit because they are closely related and because some of the later commits reverse changes in earlier commits. Changes to message and help quote display for Emacs 25 seem to be here to stay. The quote protections are required to ensure grave accents and apostrophes are displayed as intended in Emacs 25, and they should not affect earlier versions.
