Don't you want to distinguish 'kill' non-nil where the frame should get
deleted from 'kill' nil where nothing is done?  In the latter case the
window cannot even be deleted because when the return value of
'window-deletable-p' equals 'frame' this implies that WINDOW is the root
window of its frame.
