do it by hand and avoid setting w->force_start.

Select a new buffer only if w is selected window.

	argument to Qt, instead of trying to typecheck it.

	* window.c (Fdelete_windows_on): New optional argument FRAME; if
	nil, delete windows on all frames.  If t, delete windows on the
	selected frame only.  If a frame, delete windows on that frame
	only.

	* window.c (Fnext_window, Fprevious_window): Put these docstrings
	in comments; the strings are too long for some C compilers.

	any visible frame.
	* buffer.c (Fother_buffer): Pass Qt as the second argument
	to Fget_buffer_window.
	* window.c (window_loop): In GET_BUFFER_WINDOW case, ignore
	non-visible frames.
	(Fget_buffer_window): Change doc string to mention that passing Qt
	for the FRAME argument returns windows on visible frames only.
	(Qvisible): Removed.

	any visible frame.
	* buffer.c (Fother_buffer): Pass Qvisible as the second argument
	to Fget_buffer_window.
	* window.c (Qvisible): New symbol.
	(window_loop): In GET_BUFFER_WINDOW case, if frames is Qvisible,
	ignore non-visible frames.
	(Fget_buffer_window): Expand doc string to mention that Qvisible
	is an interesting value for FRAME argument.
	(syms_of_window): Init and staticpro Qvisible.
	* lisp.h (Qvisible): New declaration.

(Fdelete_window): Mostly undo last change which made `frame' a FRAME_PTR.
Don't initialize `frame' in the declaration.

	if the frame has a minibuffer; FRAME_MINIBUF_WINDOW points to the
	surrogate on minibufferless frames, not nil.

(Fscroll_right): Ditto.

(Fprevious_window): When changing frames,
use the new frame's minibuffer if any.

to have a buffer, always give it one.

(syms_of_window): Always defvar pop-up-frames
and pop-up-frame-function.

(syms_of_window): Don't make it  Lisp var.

we connect it to a new buffer.

(Fset_window_configuration): Likewise.

	`frame-live-p'.
	* window.c (Fwindow_live_p): Renamed from Flive_window_p.
	* lisp.h (CHECK_LIVE_WINDOW): Change to use Qwindow_live_p.
	(Qwindow_live_p): Extern declaration renamed fom Qlive_window_p.

	* alloc.c, frame.c, frame.h, indent.c, keyboard.c, keyboard.h,
	lisp.h, term.c, termhooks.h, window.c, window.h, xdisp.c, xfns.c,
	xterm.c, xterm.h: Terminology changed.

	number of arguments to unbind_to.
	* lread.c (Feval_buffer): Same.
	* window.c (Fscroll_other_window): Same.

	* window.c (Fset_window_configuration): Pass the proper number of
	arguments to Fselect_frame.

	XWINDOW to selected_window before passing it to window_internal_width.
