This consolidates the test made in those two functions so as to make
sure they agree whether a window needs to be redisplayed.
At the same time, change this test so it uses the window's point
rather than the buffer's point when comparing to `w->last_point`.
* src/xdisp.c (needs_no_redisplay): New function, extracted from
`redisplay_window`.

* src/window.c (window_point): New function, extracted from `Fwindow_point`.
(Fwindow_point): Use it.
* src/window.h (window_point): Declare it.
Move that function next to its siblings. Also simplify it, since
after careful analysis it is now clear that the frame's title's update
is already handled elsewhere (in `prepare_menu_bars` and `redisplay_window`)
so we just need to make sure the `redisplay` bit is set.
* src/window.c (wset_update_mode_line): Move to `src/xdisp.c`.

(move_minibuffer_onto_frame): Set the major mode of *Minibuf-0*.
(Fminibuffer_innermost_command_loop_p): New primitive.
(Fabort_minibuffers): Check the command loop level before throwing t to 'exit,
and set minibuffer_quit_level too.
(read_minibuf): New variable calling_window.
Before stacking up minibuffers on the current mini-window, check that the
mini-window is not the current one.
Do not call choose_minibuf_frame from read_minibuf's unwinding process.
Bind calling_frame and calling_window over the recursive edit.
Set the new minibuffer's major mode directly.
Remove the switching away from the minibuffer after the recursive edit.
(get_minibuffer): Record the command loop level in new variable
Vcommand_loop_level_list. No longer set the major mode of a returned
minibuffer.
(minibuf_c_loop_level): New function.
(read_minibuf_unwind): New variables calling_frame, calling_window are unbound
from the binding stack. Remove old variable `window', which could not be set
reliably to the expired mini-window.
The expired minibuffer is determined as the nth in the list, rather than the
contents of the current or previous mini-window.
Switch the current window away from the mini-window here (moved from
read_minibuf).
In particular, add a new value to the variable, and fix several bugs apparent
with the implementation up till now.
* doc/emacs/mini.texi (Basic Minibuffer): Add a description of the new
non-nil, non-t value of minibuffer-follows-selected-frame.

minibuffers.

minibuffer" with "a minibuffer".

description of the new non-nil, non-t value.
* lisp/cus-start.el (top level): make the customize entry for

value of minibuffer-follows-selected-frame.
(choose_minibuf_frame): check (minibuf > 1) in place of (minibufer > 0) at a
particular place. At another place, check that an alleged frame is so and is
live. Before selecting a non-miniwindow on a different frame, ensure it
really is a different frame.
(move_minibuffer_onto_frame): Stack up all recursive minibuffers on the target
frame. Check the minibuf_window isn't in the old frame before setting that
frame's miniwindow to an inactive minibuffer.
(Finnermost_minibuffer_p, Fabort_minibuffers): New primitives.
(this_minibuffer_depth): New function.
(read_minibuf): Record the calling frame in a variable, and switch back to it
after the recursive edit has terminated normally, using
select-frame-set-input-focus. Stack up all the recursive minibuffers on the
miniwindow where a new minibuffer is being opened. After the recursive edit,
switch the selected window away from the expired minibuffer's window.
(nth_minibuffer): New function.
(minibuffer-follows-selected-frame): Change from a DEFVAR_BOOL to a
DEFVAR_LISP.
* src/window.c (decode_next_window_args): Set *minibuf to w's mini-window's
content when that content is a minibuffer.
* src/window.h (minibuf_level) Declaration moved from here to lisp.h.

minimum height is one line.

of mini windows more accurately.

All uses changed.
(GCALIGNED_STRUCT_MEMBER, GCALIGNED_STRUCT, GCALIGNED): New macros.
All uses of open-coded GCALIGNED changed to use GCALIGNED.
(union vectorlike_header): No longer GC-aligned.
(PSEUDOVECSIZE): Yield 0 for pseudovectors without Lisp
objects that place a member before where the first Lisp object
member would be.
Instead of using __builtin_assume_aligned (P, GCALIGNMENT) to
tell GCC that P has alignment 8, use (T *) P where T is the
type of the pointed-to object, to tell GCC that P has native
alignment. This is simpler, matches the intent better, and
should help simplify future improvements. Some of these
changes are to pacify gcc -Wnull-dereference, since GCC is
smarter about pointers now that Emacs no longer uses
__builtin_assume_aligned; these minor changes should improve
code efficiency slightly. On Fedora 28 x86-64 with default
optimization this patch shrinks the size of the Emacs text
segment by 0.36%.
* src/conf_post.h (__has_builtin, __builtin_assume_aligned):
Remove; no longer used.

Simplify by using LISP_WORD_TAG.

Pacify -Wnull-dereference by using XCAR instead of Fcar and

tooltips and vice-versa in x_hide_tip (Bug#30399).
* src/window.h (struct window): New Lisp member
mode_line_help_echo.
(wset_mode_line_help_echo): New function.
* src/w32fns.c (Fx_show_tip): Normalize the FRAME argument
bevore storing it in tip_last_frame (Bug#30399).
* src/xdisp.c (display_mode_lines): Calculate mode line
default help echo string here and store it in the window's
mode_line_help_echo slot (Bug#30182).
(note_mode_line_or_margin_highlight): Use value in window's
mode_line_help_echo slot as mode line default help echo. When
the window is resizable show a vertical drag cursor instead of
the vertical scroll bar cursor.
* src/xfns.c (x_hide_tip): Rewrite the GTK+ part to correctly
handle the transition from GTK+ system to Emacs tooltips and
vice-versa (Bug#30399).
(Fx_show_tip): Normalize the FRAME argument bevore storing it
in tip_last_frame (Bug#30399).
* src/buffer.h (bset_left_margin_cols, bset_right_margin_cols):
New inline functions.
* src/xfns.c (Fx_show_tip):
* src/w32fns.c (Fx_show_tip): Force display margins of the tip
buffer to zero, as it will be displayed in a pseudo-window, which
doesn't support display margins. (Bug#29627)
