* src/editfns.c (format_time_string, Fcurrent_time_zone): Pass a
pointer to time_t value to emacs_localtime_rz and gmtime_r,
instead of relying on struct timespec's tv_sec member to be of
compatible type.
* src/editfns.c (Fformat): Fix ambiguity in the doc string's usage
of a literal period. (Bug#24407)
This was backported from master
(cherry picked from commit 7123896626)
* src/fileio.c (Fwrite_region): Clarify that END is ignored if
START is nil.
* src/editfns.c (Fbuffer_size): Add short discussion about
narrowing.
* src/callproc.c (Fcall_process_region): Discuss behavior when
START and END are not buffer positions.
It's important to adjust the match data in between calling
before-change-functions and after-change-functions, so that buffer
change hooks will always see match-data consistent with buffer content.
(Bug #23917)
* src/insdel.c (replace_range): Add new parameter ADJUST_MATCH_DATA, if
true call update_search_regs. Update all callers (except
Freplace_match) to pass 0 for the new parameter.
* src/search.c (update_search_regs): New function, extracted from
Freplace_match.
(Freplace_match): Remove match data adjustment code, pass 1 for
ADJUST_MATCH_DATA to replace_range instead.
* src/editfns.c (Ftranspose_regions): Regions may overlap, so
use memmove instead of memcpy (bug#19213).
Copyright-paperwork-exempt: yes

Work around Bug#22884 by rewording comments and strings to avoid ‘(’
at the start of a line unless it starts a function. This change
is a short-term hack; in the longer run we plan to fix cc-mode’s
performance for C files that have ‘(’ at the start of a line in a
comment or string.
Omit ‘#include "foo.h"’ unless the file needs foo.h (Bug#21707).
In a few cases, add ‘#include "foo.h"’ if the file needs foo.h
but does not include it directly. As a general rule, a source
file should include foo.h if it needs the interfaces that foo.h
defines.

Although \( is needed in docstrings in Elisp code, it is not needed in
docstrings in C code, since C function definitiions do not start with
a parenthesis. The backslashes made the docstrings a bit harder to
read and to format in columns. Also, some C docstrings had ( in
column 1 and this did not appear to be causing any problems. So,
simplify C docstrings by replacing \( with ( and \) with ).
* src/editfns.c (styled_format): Refactor internally, mostly by
moving declarations closer to uses. This should not affect behavior.
* test/automated/textprop-tests.el (textprop-tests-format): New test.

* src/bytecode.c (relocate_byte_stack):
Rename from unmark_byte_stack, since it now only relocates.
All callers changed.

This means we no longer need %qs, so remove that format.
While we’re at it, fix an unlikely bug and lessen the pressure
on the garbage collector by processing the string once rather
than twice in the usual case.

followed by Fformat.
* src/doc.c (LSQM, RSQM): Remove; all uses changed to use
uLSQM and uRSQM.
(Fsubstitute_command_keys): Prefer AUTO_STRING to build_string
when pure ASCII now suffices. Fix unlikely bug when parsing
unibyte string containing non-ASCII bytes. Use inline code
rather than memcpy, as it’s a tiny number of bytes.
(Finternal__text_restyle): Remove; no longer used.
(syms_of_doc): Don’t declare it.
* src/editfns.c (Fformat): Rewrite in terms of new function
‘styled_format’.
(Fformat_message): New function, moved here from subr.el.

except it now optionally transliterates quotes, and it transliterates
traditional grave accent and apostrophe quoting as well.
Remove recently-added q flag; no longer needed or used.
(syms_of_editfns): Define format-message.
* src/lisp.h (uLSQM0, uLSQM1, uLSQM2, uRSQM0, uRSQM1, uRSQM2):
Remove; no longer need to be global symbols.
* src/xdisp.c (vadd_to_log): Use Fformat_message, not Fformat,
so that callers can use `%s'.
* src/image.c (image_size_error, xbm_load_image, xbm_load)
(xpm_load, pbm_load, png_load_body, jpeg_load_body, tiff_load)

* src/lread.c (load_warn_old_style_backquotes):

Use `%s' instead of %qs in formats.
This is a followup to the recent doc string change, and deals with
diagnostics and the like. This patch is more conservative than
the doc string change, in that the behavior of ‘format’ changes
only if its first arg contains curved quotes and the user prefers
straight or grave quotes. (Come to think of it, perhaps we should
be similarly conservative with doc strings too, but that can wait.)
The upside of this conservatism is that existing usage is almost
surely unaffected. The downside is that we'll eventually have to
change Emacs's format strings to use curved quotes in places where
the user might want curved quotes, but that's a simple and
mechanical translation that I'm willing to do later. (Bug#21222)

DEFSYM Qdeactivate_mark before the corresponding var.
* keymap.c (syms_of_keymap): Use DEFSYM for Qmenu_bar and Qmode_line
instead of interning their symbols; this avoids duplicates.
(LISP_INITIALLY, TAG_PTR)
(DEFINE_LISP_SYMBOL_BEGIN, DEFINE_LISP_SYMBOL_END, XSYMBOL_INIT):
New macros.
(LISP_INITIALLY_ZERO): Use it.
(enum symbol_interned, enum symbol_redirect, struct Lisp_Symbol)
(EXFUN, DEFUN_ARGS_MANY, DEFUN_ARGS_UNEVALLED, DEFUN_ARGS_*):
Move decls up, to avoid forward uses. Include globals.h earlier, too.
(make_lisp_symbol): New function.
(XSETSYMBOL): Use it.
(DEFSYM): Now just a placeholder for make-docfile.
* lread.c (DEFINE_SYMBOLS): Define, for globals.h.
(intern_sym): New function, with body taken from old intern_driver.
(intern_driver): Use it. Last arg is now Lisp integer, not ptrdiff_t.
All uses changed.
(define_symbol): New function.
(init_obarray): Define the C symbols taken from lispsym.
Use plain DEFSYM for Qt and Qnil.
* syntax.c (init_syntax_once): No need to worry about
Qchar_table_extra_slots.
Also, the system-name variable is now obsolete.
Fixes Bug#19438.

Prefer (system-name) to system-name, and avoid naming
locals 'system-name'.
* doc/misc/smtpmail.texi (Server workarounds): Fix grammar.
* lisp/startup.el (system-name): Now an obsolete variable.
* src/editfns.c (cached_system_name): New static var.
(init_and_cache_system_name): New function.
(init_editfns, Fsystem_name): Use it.
(syms_of_editfns): Initialize it and Vsystem_name to the same value.
* src/sysdep.c [HAVE_SOCKETS]: Don't include <sys/socket.h>, <netdb.h>.
(h_errno) [TRY_AGAIN && !HAVE_H_ERRNO]: Remove decl.
(init_system_name) [HAVE_SOCKETS]: Don't canonicalize the name.
Don't create a new string if the current value is already correct.
This implements a suggestion made in:
http://lists.gnu.org/archive/html/emacs-devel/2014-10/msg00587.html
Among other things, this means timer.el no longer needs to
autoload the time-date module.
* doc/lispref/os.texi (Time of Day, Time Conversion, Time Parsing)
(Processor Run Time, Time Calculations):
Document the new behavior, plus be clearer about the old behavior.
(Idle Timers): Take advantage of new functionality.
* etc/NEWS: Document the changes.
* lisp/allout-widgets.el (allout-elapsed-time-seconds): Doc fix.

* lisp/timezone.el (timezone-time-from-absolute):
* lisp/type-break.el (type-break-schedule, type-break-time-sum):
Simplify by using new functionality.
* lisp/calendar/cal-dst.el (calendar-next-time-zone-transition):
Do not return time values in obsolete and undocumented (HI . LO)
format; use (HI LO) instead.
* lisp/calendar/time-date.el (with-decoded-time-value):
Treat 'nil' as current time. This is mostly for XEmacs.
(encode-time-value, with-decoded-time-value): Obsolete.
(time-add, time-subtract, time-less-p): Use no-op autoloads, for
XEmacs. Define only if XEmacs, as they're now C builtins in Emacs.
* lisp/ldefs-boot.el: Update to match new time-date.el
* lisp/proced.el: Do not require time-date.
* src/editfns.c (invalid_time): New function.
Use it instead of 'error ("Invalid time specification")'.
(time_add, time_subtract, time_arith, Ftime_add, Ftime_less_p)
(decode_float_time, lisp_to_timespec, lisp_time_struct):
New functions.
(make_time_tail, make_time): Remove. All uses changed to use
new functions or plain list4i.
(disassemble_lisp_time): Return effective length if successful.
Check that LOW is an integer, if it's combined with other components.
(decode_time_components): Decode into struct lisp_time, not
struct timespec, so that we can support a wide set of times
regardless of whether time_t is signed. Decode plain numbers
as seconds since the Epoch, and nil as the current time.
(lisp_time_argument, lisp_seconds_argument, Ffloat_time):
Reimplement in terms of new functions.
(Fencode_time): Just use list2i.
(syms_of_editfns): Add time-add, time-subtract, time-less-p.
* src/keyboard.c (decode_timer): Don't allow the new formats (floating
point or nil) in timers.
* src/systime.h (LO_TIME_BITS): New constant. Use it everywhere in
place of the magic number '16'.
(struct lisp_time): New type.
(decode_time_components): Use it.
(lisp_to_timespec): New decl.
* lisp.h (scan_newline_from_point): Add prototype.
* search.c (scan_newline_from_point): New function, refactored from...
* cmds.c (Fforward_line): ...adjusted user.
* editfns.c (Fline_beginning_position): Use scan_newline_from_point
and simplify the former since the latter doesn't move point.
