bug#12380: other window related commands broken

[Doug Morgan <dougrm@sprynet.com>]

I had only tested it with "emacs -q" (forgot about the Q version).  
However, retesting with "emacs -Q" gives the same behavior.  Also, the 
menu only has "Send Bug Report..." which doesn't work for me "Wrong type 
argument: string, nil" after I enter a subject title (never having set 
up emacs to handle mail).

Inside the unsent email buffer was this interesting looking text (and it 
looked like it would go to bug-gnu-emacs@gnu.org so I'm cc'ing that:
