Refresh .emacs prologue
The stuff about package-initialize is flat out wrong:
(a) package-initialize is _not_ called automatically at startup;
(b) for all that, customizations seem none the worse for wear.
'(elisp) Packaging Basics' suggests that Emacs does automatically call
'package-activate-all' (unless asked otherwise in the early init file)
so it's really not clear what that business with package-initialize
was about 🤷
Add some more up-to-date commentary regarding other topics.
