If one has a very quick eye, one can discover M-x man "zzzyyyxxx"
repaints the entire screen before declaring in the minibuffer "No manual
entry for zzzyyyxxx". Doesn't seem very efficient.
Also one thinks the man page is coming in and looks at the screen, but
in fact it is just the screen being repainted. emacs-version "25.1.1"
