bug#7600: 24.0.50; Incorrect value shown in Customize after setq

[Drew Adams]

emacs -Q
M-: (setq mouse-buffer-menu-mode-mult t)
 
Note that that value is invalid wrt the defcustom.
 
C-h v mouse-buffer-menu-mode-mult
 
 mouse-buffer-menu-mode-mult is a variable defined in `mouse.el'.
 Its value is t
 Original value was 4
 
M-x customize-option mouse-buffer-menu-mode-mult
 
The Customize buffer shows this:
 
   Hide mouse-buffer-menu-mode-mult: 4
    State : CHANGED outside Customize. (mismatch)
   Group the buffers by the major mode groups...
 
C-h v still shows the same thing - the value is t.
M-: mouse-buffer-menu-mode-mult ; confirms the value is t
 
The Customize buffer should show the value as what it is: t.  Then it is
correct to show "(mismatch)".  But 4 is incorrectly shown as the value.
And 4 would _not_ be a mismatch.
 

Also: `Hide' is placed poorly in the UI.  It has the same font etc. as
the ordinary text.  So it is simply read as text, and the result makes
no sense when read.
