[$] Toward a "modern" Emacs

It has only been a few months since the Emacs community went through an extended discussion on how to make the Emacs editor "popularagain". As the community gears up for the Emacs 28 development cycle,(after the Emacs27.1 release in August)that discussion has returned with a vengeance. The themes of thisdiscussion differ somewhat from the last; developers are concerned aboutmaking Emacs - an editor with decades of history - seem "modern" to attractnew users.
