* lisp/progmodes/cc-cmds.el (c-defun-name): Use
c-back-over-compound-identifier in place of c-backward-token-2 near the end
of the function.

* test/Makefile.in (%.log): Move setting of HOME here from top-level.

Without this patch, ‘make check’ can fail with the diagnostic
‘invalid syntax in conditional’ if there is an Emacs temporary
file whose name starts with ‘.#’, because the ‘#’ is treated as
the start of a Make comment.
* lisp/Makefile.in (loaddefs, tagsfiles, check-defun-deps):
* test/Makefile.in (ELFILES):
Skip files starting with ‘.’, so that the .#* files do not cause
trouble.  (We cannot easily skip just files starting with ‘.#’,
since ‘#’ starts a Make comment!)

* lisp/bindings.el (mode-line-percent-position): give it a
`risky-local-variable' property.
(mode-line-position): correct the quoting on the mode-line-percent-position
part of the variable, allowing the properties to be properly recognized.

* lisp/bindings.el (mode-line-percent-position): give it a
`risky-local-variable' property.
(mode-line-position): correct the quoting on the mode-line-percent-position
part of the variable, allowing the properties to be properly recognized.

* build-aux/config.guess: Copy from gnulib.
* lib/gnulib.mk.in: Regenerate.

* test/Makefile.in (HOME): Export a non-existent value.

* .gitattributes: Remove nt/nmake.defs.  Move dostorture.c, c.C,
algrthms.html.  Use pattern for todo-mode.  Improve patterns for
Ada, C, ObjC, shell.  Add Pascal.  Remove unused pattern *.ruby.
Add config.guess and config.sub as shell files.

* doc/emacs/cmdargs.texi (Initial Options):
* doc/lispref/os.texi (Startup Summary):
* etc/NEWS:
* etc/emacs.service:
* src/emacs.c (main):
* src/lisp.h: Rename '--new-daemon' to 'fg-daemon' and '--old-daemon' to
'--bg-daemon'.

* test/lisp/calendar/todo-mode-tests.el (todo-test-todo-quit02)
(todo-test-item-highlighting): Avoid prompting for input file.

* src/.gdbinit (to_string): Use an unsigned representation for
Lisp values, as requested by Eli Zaretskii (Bug#27098).
Also, use "make_number(N)" for Lisp integers.

* lisp/emacs-lisp/eldoc.el (global-eldoc-mode):
Turn into globalized mode (bug#19853).
(turn-on-eldoc-mode): Make it into a wrapper instead of alias.
(eldoc-mode): Only show the message when called interactively.

* lisp/progmodes/xref.el (xref-collect-matches):
See if the output buffer contents look like Grep output
instead of checking exit status (bug#23451).

*test/lisp/calendar/todo-mode-tests.el:
*test/lisp/calendar/todo-mode-resources/todo-test-1.toda:
*test/lisp/calendar/todo-mode-resources/todo-test-1.todo: New files.

* .gitattributes: Ignore trailing whitespace in todo-mode test
data files, since it is part of the todo-mode file format.

* lisp/calendar/todo-mode.el (todo-hl-line-range): New named function,
replacing an anonymous function for the sake of `describe-variable'.
(todo-modes-set-2): Use it as buffer-local value of hl-line-range-function
and remove boundp test of this variable, so its value is available on
invoking `todo-toggle-item-highlighting'.

* src/nsfns.m (compute_tip_xy): Cast NSRect to CGRect and NSPoint to
CGPoint.

* test/lisp/progmodes/python-tests.el (python-indent-after-backslash-1)
(python-indent-after-backslash-2)

(python-info-continuation-line-p-1)
(python-info-block-continuation-line-p-1)
(python-info-assignment-statement-p-1)
(python-info-assignment-continuation-line-p-1): Backslashes in
literals should be doubled only once to produce one backslash in the
buffer.  If there backslashes inside a Python string literal in a Lisp
literal, that would need to be doubled twice, but there are no such
cases.  Note that `python-tests-looking-at' takes a plain string, not
a regexp.

* test/lisp/progmodes/python-tests.el
(python-indent-after-backslash-4): Indent after backslash is now
python-indent-offset.

* lisp/progmodes/python.el (python-indent--calculate-indentation):
Increase indent by `python-indent-offset' after
`:after-backslash-assignment-continuation'.

* lisp/subr.el (interactive-p): Mention commandp, as this is often
  what users are actually looking for.

* lisp/button.el (button-get): Previously we assumed that button-get
  was called in the buffer containing the button.  In other buffers,
  button-get always returned nil.  Fix this by passing the relevant
  buffer from the marker.

* lisp/progmodes/xref.el (xref-collect-matches): Signal error
if find-grep returns a nonzero status (bug#23451).  Remove the
comment: even if some output is present, a non-zero status
means something went wrong and it can't be relied upon.

This failed due to commit ea3ae33b from 2013-05-16, which prevented
quitting todo-mode buffer after visiting todo-archive buffer from
making the archive buffer current again.  Avoid this now by simply
killing the archive buffer, since there's no need to keep it a live
buffer.  Consequently, quitting a todo-mode buffer can now use
bury-buffer without an argument, which ensures that is will not
becomes current on quitting the buffer that replaced it in the window.

* lisp/calendar/todo-mode.el (todo-quit): Kill todo-archive-mode
buffer instead of burying it.  This now allows exiting the
todo-mode buffer by bury-buffer without an argument, so do that.

* lisp/net/tramp-adb.el (tramp-adb-parse-device-names):
Use `make-tramp-file-name'.
(tramp-adb-get-device): Use `tramp-file-name-port-or-default'.
(tramp-adb-maybe-open-connection): Set "prompt" property.
(tramp-adb-wait-for-output): Use it.

* lisp/net/tramp-cache.el (tramp-cache-print): Use `elt'.
(tramp-dump-connection-properties): Check also that there are
properties to be saved.  Don't save "started" property of
"ftp" method.

* lisp/net/tramp-gvfs.el (tramp-gvfs-handle-expand-file-name):
Use `make-tramp-file-name'.

* lisp/net/tramp.el (tramp-remote-file-name-spec-regexp):
Host could be empty.
(tramp-file-name-port-or-default): New defun.
(tramp-dissect-file-name): Simplify `make-tramp-file-name' call.
(tramp-handle-file-name-case-insensitive-p): Use a progress reporter.
(tramp-call-process, tramp-call-process-region):
Use `make-tramp-file-name'.

* test/lisp/net/tramp-tests.el (tramp-test03-file-name-defaults):
Revert change from 2017-05-24.
(tramp-test05-expand-file-name-relative): Let it also pass for
"adb" method.

* tramp-adb.el (tramp-adb-ls-toolbox-regexp):
Username part of prompt is empty on Android 7.
(tramp-adb-ls-toolbox-regexp):
Ignore addition links column on Android 7.
(tramp-adb-get-ls-command):
Dont use --color=none when using toybox (Android 7).  It's not
possible to disable coloring explicitly for toybox ls.

* lisp/emacs-lisp/cl-indent.el (lisp-extended-loop-p): Allow for
":keywords".

Use IN_MASK_ADD instead of using a no-longer-promiscuous-enough
mask.  This simplifies the code and restores the ability to
use IN_ACCESS, IN_CLOSE_WRITE, IN_CLOSE_NOWRITE, and IN_OPEN
in some cases (Bug#26973).
* src/inotify.c (INOTIFY_DEFAULT_MASK): Remove.
(Finotify_add_watch): Use IN_MASK_ADD instead.

There was no need to remove it in the 2017-03-26 inotify change,
as it is like IN_DONT_FOLLOW and does not affect other watchers
for the same file.
* src/inotify.c (symbol_to_inotifymask, Finotify_add_watch)
(syms_of_inotify): Bring back onlydir.

* src/inotify.c (add_watch): Accept uint32_t imask instead
of Lisp_Object aspect.  Caller changed.
(Finotify_add_watch): Use aspect_to_inotifymask earlier, to
simplify the code.

These functions can only be run in batch mode and exit Emacs on
return, so nothing can be recovered.  Disable unsafe recover
mechanisms so that we get real failures and good stack traces on
fatal signals.

* lisp/emacs-lisp/bytecomp.el (batch-byte-compile)
(batch-byte-recompile-directory):
* lisp/emacs-lisp/ert.el (ert-run-tests-batch-and-exit)
(ert-summarize-tests-batch-and-exit): Don't attempt to recover
from undefined behavior.

When configured with --without-ns, HAVE_NS is not defined on macOS,
thus 'memory-limit' calls the deprecated sbrk(2) function.  Avoid that
by using the pre-defined __APPLE__ preprocessor macro.

* src/alloc.c (Fmemory_limit): Never use sbrk(2) on macOS.

* lisp/ruler-mode.el (ruler-mode-text-scaled-width): New function
for computing scaled text width.
(ruler-mode-text-scaled-window-hscroll)
(ruler-mode-text-scaled-window-width): Compute text scaled
`window-width' value.
(ruler-mode-mouse-grab-any-column, ruler-mode-mouse-add-tab-stop)
(ruler-mode-ruler): Change `window-hscroll' into
`ruler-mode-text-scaled-window-hscroll', and change `window-width'
into `ruler-mode-text-scaled-window-width'.

* src/window.c (Fset_window_scroll_bars): Fix doc-string.

* doc/lispref/display.texi (Fringe Size/Pos, Scroll Bars)
(Display Margins): Mention that `set-window-buffer' may override
settings made by `set-window-fringes', `set-window-scroll-bars'
and `set-window-margins'.
* doc/lispref/windows.texi (Buffers and Windows): Fix doc of
`set-window-buffer'.

* src/keyboard.c (echo_truncate): Don't call Ftruncate if the echo
message is already shorter than NCHARS.  (Bug#27040)

* lisp/progmodes/gud.el (gud-menu-map): Don't call gdb-show-stop-p
when GUD mode is 'pdb'.  (Bug#27024)

* doc/emacs/frames.texi (Drag and Drop): Document support of drag
and drop region by mouse.
* lisp/mouse.el (mouse-drag-region): Call mouse-drag-and-drop-region
when start-event is on region.
(mouse-drag-and-drop-region): New function, moves the region by
(mouse-drag-and-drop-region): New defcustom.
* etc/NEWS: Mention mouse-drag-and-drop-region.
