	(frame-initialize): Use minibuffer-frame-list, instead of writing
	it out.
	(frame-notice-user-settings): Thoroughly rearranged.
	Notice changes to default-frame-alist as well as initial-frame-alist.
	Properly handle requests to make the initial frame into a
	minibufferless or minibuffer-only frame.

	minibuffer and there are no other minibuffer frames created by the
	user's initialization file.
	Fix any frames using the initial frame as a surrogate minibuffer
	frame.
	Restore the current buffer after creating and deleting all these
	frames.

	set-frame-foreground, set-cursor-color, set-pointer-color,

	set-horizontal-bar): Give these docstrings.
