bug#12311: 24.1.50; z in special-mode-map

[Richard Stallman <rms@gnu.org>]

I just discovered why some of the Dired buffers I always keep
occasionally disappear.  It is because the binding of z in
special-mode-map makes it so easy to kill them.

I just got rid of that binding in my .emacs, but I think that binding
is a bad idea.  Not all the buffers in special modes are things people
don't mind deleting, and this key can cause annoyance if typed by
accident.
