(fill-delete-newlines): Call sentence-end as function.
(fill-nobreak-p, canonically-space-region): Likewise.
(fill-nobreak-p): If this break point is at the end of the line,
don't consider the newline which follows as a reason to return t.
(Window Point): Mention return value of `set-window-point'.
(Window Start): `pos-visible-in-window-p' disregards horizontal
scrolling. Explain return value if PARTIALLY is non-nil.
(Vertical Scrolling): Mention PIXELS-P argument to `window-vscroll'
and `set-window-vscroll'.
(Size of Window): The argument WINDOW to `window-inside-edges',
`window-pixel-edges' and `window-inside-pixel-edges' is optional.
(Resizing Windows): Explain return value of
`shrink-window-if-larger-than-buffer'.
`window-size-fixed' automatically becomes buffer local when set.
(Window Configurations): Explain return value of `set-window-configuration'.
ReceiveNextEvent to prevent breakage. Correctly handle
blocking on event queue only by calling ReceiveNextEvent
instead of select (since GUI events aren't on an fd).
(sys_read): Remove function
sysdep.c: Remove redefine of read to sys_read if HAVE_CARBON
with alarm based polling.
mac.c (sys_select): Redo sys_select to use alarm-based
polling instead of 1 sec timeouts (like solaris).
macterm.c (x_make_frame_visible): Comment in polling on
frame creation.
keyboard.c: Undef SIGIO on Carbon
atimer.c (alarm_signal_handler): Call alarm handlers after
scheduling.
eval.c (Feval): Remove quit_char test
process.c (wait_reading_process_input): Remove clearing
stdin for select call on process input
(tramp-handle-verify-visited-file-modtime): Remove
outdated comment.
(tramp-locked, tramp-locker): New variables for implementing a
global lock.
(tramp-sh-file-name-handler): Use them to implement the global
lock.
Bugfix for marking up the definition for an empty function.
New category "potentially-1valued" for functions that are not erroneous if either 1-valued or multi-valued.
Init to beginning-of-buffer and end-of-buffer.
(cua--undo-push-mark): New defvar.
(cua--pre-command-handler): Set inhibit-mark-movement if mark is
already active and command is in cua--preserve-mark-commands.
Also fix check for shift modifier on non-window systems.
(cua--post-command-handler): Clear inhibit-mark-movement if set.
