Set the field stickiness correctly from overlay fields.
Use renamed `text_property_stickiness'.
(text_property_stickiness):
Renamed from `char_property_stickiness'.
selected window.
(save_excursion_restore): If buffer was visible in a window, and a
different window was selected, and the old selected window is
still live, restore point in that window.
(save_restriction_restore): Rewrite to understand new form of data
saved by save_restriction_save.
(Fsave_restriction): Remove cautionary note in doc-string.
(Fconstrain_to_field): Add the INHIBIT-CAPTURE-PROPERTY argument.
Use scan_buffer instead of find_before_next_newline, because it
allows us to detect the boundary case where there's a newline at
the search limit.
(Qboundary): New variables.
(syms_of_editfns): Initialize Qboundary.
Renamed from `text_property_eq' and `text_property_stickiness', respectively.
(find_field, Fconstrain_to_field, char_property_eq, char_property_stickiness):
Changed to call char-property functions instead of text-property-only ones.
Lisp_Object boolean value.
(Fformat): Use a temporary variable to avoid ENABLE_CHECKING problems reading
from and changing the same lisp value in an XSETSTRING call.
(inhibit-field-text-motion): New DEFVAR_LISP.
(Fline_beginning_position, Fline_end_position): Notice field
boundaries only if inhibit-field-text-motion is nil.
* fileio.c (strerror): Likewise.
* process.c (strerror): Likewise.
* emacs.c (strerror): Likewise.
(Vsystem_messages_locale): Renamed from Vmessages_locale.
All uses changed.
(Vprevious_system_messages_locale): Likewise, from
Vprevious_messages_locale.
(Vsystem_time_locale): Likewise, from Vtime_locale.
(Vprevious_system_time_locale): Likewise, from Vprevious_time_locale.
(ABORT_RETURN_TYPE): New macro.
(abort): Return type is now ABORT_RETURN_TYPE.
(main): Always invoke init_signals, even if POSIX_SIGNALS is not
defined.
(syms_of_emacs): messages-locale -> system-messages-locale,
previous-messages-locale -> previous-system-messages-locale,
time-locale -> system-time-locale,
previous-time-locale -> previous-system-time-locale.
* gmalloc.c (PP, __ptr_t): Assume ANSI C if STDC_HEADERS is defined.
(const): Do not define; that's config.h's job.
(<limits.h>): Include if HAVE_LIMITS_H is defined.
(CHAR_BIT): Move test for definedness outside of limits.h condition.
(<stddef.h>): Include if STDC_HEADERS is defined.
(FREE_RETURN_TYPE): New macro.
(free): Return type is now FREE_RETURN_TYPE.
* lisp.h (synchronize_system_time_locale): Renamed from
synchronize_time_locale. All uses changed.
(synchronize_system_messages_locale): Likewise, from
synchronize_messages_locale.
* process.c (sys_siglist): Remove.
* syntax.c (scan_sexps_forward): Use abort, not assert.
* sysdep.c (my_sys_siglist): New var.
(sys_siglist): New macro. Remove old initialized vars of same name.
(init_signals): Initialize sys_siglist.
* xfns.c (abort): Remove decl; stdlib.h now does this.
pass t to Fconstrain_to_field for ESCAPE-FROM-EDGE.
(preceding_pos): Function deleted.
(text_property_stickiness): Decrement POS directly.
Fix a confusion that used PT instead of POS.
(find_field): Properly handle the case
of a field boundary where `field' inherits from neither side.
(Ffield_beginning, Ffield_end): Doc fixes.
(Ferase_field, Ffield_string, Ffield_string_no_properties): Doc fixes.
