  I'm using graphical Emacs 25.3.2 on Ubuntu 16.04
  C-h k ESC waited for another key input. Upon entering the second
  ESC, I get ESC-ESC is undefined. (should have allowed a third ESC
  for keyboard-escape quit).
  
  This suggested to me that prior "twiddling" (rather than a
  previously loaded elisp file) had caused this problem.

  So I reloaded the exisiting emacs configuration, and then compiled
  and reloaded the source and the problem is solved.

  I believe that I must have executed something like
  (global-set-key (kbd "C-[") 'foo) 
  ;; "C-[" translates to ESC on my system

  which I would guarantee would clobber sequences starting with ESC for sure.
  Sorry, :) Never mind!
