bug#11567: 24.0.97; WTF? ROFL! (hilarious bug)

[Tobias Bading <tbading@web.de>]

Boys & girls, please *do* try this at home! (Or whereever your Emacs is :-). Works with r108017 of the emacs-24 branch on GNU/Linux as well as Mac OS for me.)

emacs -Q:
C-h v TAB C-x o C-x 0

Your Emacs frame should now contain a single window with a completion list of variables.
Take your pick: Select any variable either with your mouse, trackpad or keyboard.... Oooops! :-D

Have fun,
Tobias

PS: New package hide-and-seek.el maybe? ;-)
