Copy from gnulib.
* src/w32fns.c (syms_of_w32fns) <w32-disable-abort-dialog>: New
variable.
(emacs_abort): If w32-disable-abort-dialog is non-nil, abort right
away, without displaying the Abort dialog, which waits for the user.
* test/src/emacs-module-tests.el (module--test-assertion): Run the
inferior Emacs with the w32 abort dialog disabled. Expect the
status of the aborted Emacs sub-process to be 3 on MS-Windows and
2 on MS-DOS.

(dired-delete-file): Use it. Dont't ask for empty dirs (Bug#27940).
* test/lisp/dired-tests.el (dired-test-with-temp-dirs):
New auxiliar macro.
(dired-test-bug27940): Add new test.
There are a number of places where eval is used unnecessarily to get
or set the value of a symbol.
* lisp/calendar/calendar.el (diary-date-forms): Use default-value in
custom setter.
* lisp/desktop.el (desktop-clear): Use set-default instead.
* lisp/international/ogonek.el (ogonek-read-encoding): Use
symbol-value.
* lisp/emulation/viper-ex.el (viper-get-ex-token): Bind
(following-char) and use it in the subsequent cond's clauses.
(viper-ex, ex-quit, viper-get-ex-file): Use following-char instead.
Convert single branch ifs to when
* doc/lispref/files.texi (Unique File Names):
* src/fileio.c (Fmake_temp_name): Document that make-temp-name
does not guarantee uniqueness on magic file names.
Bug#25354

(compilation-face): Remove.
(compilation-type, compilation--note-type): New functions.
(compilation-parse-errors): Call compilation--note-type.
(compilation-start): Include compilation-mode-line-errors in
mode-line-process.
(compilation-setup): Initialize compilation-num-* variables to 0.
(compilation-handle-exit): Include compilation-mode-line-errors in

(mailcap-parse-mimetype-file): Just use append.
(mailcap-command-p): Remove unused function.
During a `query-replace', the char ',' replaces the character
at point and doesn't move point; right after, the char 'u'
must undo such replacement (Bug#27268).
* lisp/replace.el (replace--push-stack):
New macro extracted from `perform-replace'.
(perform-replace): Use it.
* test/lisp/replace-tests.el (query-replace--undo): Add test.
This prevents definitions being compiled from leaking into the current
Emacs doing the compilation.
* lisp/emacs-lisp/gv.el (gv-define-expander): Use function-put instead
of `put' with `eval-and-compile'.
* test/lisp/emacs-lisp/gv-tests.el: New tests.
* lisp/emacs-lisp/eieio.el (defclass): Use `define-symbol-prop'
instead of `put'.
* test/lisp/emacs-lisp/eieio-tests/eieio-tests.el

* test/lisp/dom-tests.el: Require `subr-x' during runtime as well.
* test/lisp/emacs-lisp/cl-lib-tests.el (cl-lib-defstruct-record):
* test/lisp/emacs-lisp/eieio-tests/eieio-tests.el
(eieio-test-23-inheritance-check, eieio-test-25-slot-tests): Mark as
expected to fail when byte-compiled.
This kludge catches errors caused by evaluating arguments in ert's
should, should-not, and should-error macros; it also catches
macroexpansion errors inside of the above macros (Bug#24402).
* lisp/emacs-lisp/ert.el: (ert--should-signal-hook): New function.
(ert--expand-should-1): Catch macroexpansion errors.
* test/lisp/emacs-lisp/ert-tests.el (ert-test-should-error-argument)
(ert-test-should-error-macroexpansion): Tests for argument and
expansion errors.
* lisp/textmodes/ispell.el (ispell-program-name): Add “enchant”.
(ispell-really-enchant): Add variable.
(ispell-check-version): If using Enchant, check it’s new enough (at
least 1.6.1). (Like the ispell check, this is absolute: cannot work
without.)
(ispell-enchant-dictionary-alist): Add variable.
(ispell-find-enchant-dictionaries): Add function, based on
ispell-find-aspell-dictionaries.
(ispell-set-spellchecker-params): Allow dictionary auto-detection for
Enchant, and call ispell-find-enchant-dictionaries to find them. Use
old ispell name to locale mapping code for Enchant too.
(ispell-send-replacement): Make it work with Enchant.
* lisp/simple.el (async-shell-command-display-buffer): Add
defcustom.
(shell-command): Use the new defcustom to determine whether to show
the buffer immediately, or add a process filter that shows it only
when there is some output.
* etc/NEWS: Document the new variable.
* doc/emacs/misc.texi: Likewise.
Thanks to Juri Linkov and Eli Zaretskii for advice and guidance.
* src/xdisp.c (get_overlay_strings_1)
(handle_single_display_spec, push_prefix_prop): Invalidate the
composition information before starting to iterate on a string.
Otherwise we might think in set_iterator_to_next that we are
delivering characters from a composition, and do all kinds of
nonsensical things, like over-step the string end. (Bug#27761)
* lisp/files.el (basic-save-buffer-2, move-file-to-trash):
Use make-temp-name, not make-temp-file with retry.
(basic-save-buffer-2): Use condition-case, instead of
unwind-protect with a success flag.
* lisp/progmodes/grep.el (grep-mode-font-lock-keywords): Allow for NUL
characters following filename in grep context lines.
(grep--regexp-alist-column, grep--regexp-alist-bin-matcher)
(grep-with-null-regexp-alist, grep-fallback-regexp-alist): Remove.
(grep-regexp-alist): Recombine their contents here.
(grep-mode):
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-parse-tool-output-one-line):
* lisp/progmodes/xref.el (xref-collect-matches): Use the variable
`grep-regexp-alist' rather than the function.

http://lists.gnu.org/archive/html/emacs-devel/2017-08/msg00143.html
* src/eval.c (For, Fprogn, Fsetq, FletX, eval_sub):
Compute XCDR (x) near XCAR (x); although this doesn't fix any bugs,
it is likely to run a bit faster with typical hardware caches.
(Fif): Use Fcdr instead of XCDR, to avoid crashing on
self-modifying S-expressions.
(Fsetq, Flet, eval_sub): Count the number of arguments as we go
instead of trusting an Flength prepass, to avoid problems when the
code is self-modifying.
(Fquote, Ffunction, Fdefvar, Fdefconst): Prefer !NILP to CONSP
where either will do. This is mostly to document the fact that
the value must be a proper list. It's also a tiny bit faster on
typical machines nowadays.
(Fdefconst, FletX): Prefer XCAR+XCDR to Fcar+Fcdr when either will do.
(eval_sub): Check that the args are a list as opposed to some
other object that has a length. This prevents e.g. (if . "string")
from making Emacs dump core in some cases.
* test/src/eval-tests.el (eval-tests--if-dot-string)
(eval-tests--let-with-circular-defs, eval-tests--mutating-cond):
New tests.
The mailcap minibuffer completion used dynamic binding. Locally set
a dynamic variable.
* lisp/dired-aux.el: Store list of files in
`minibuffer-completion-table'.
This action might delete directories containing valuable information.
Before previous commit, we prompted users with `yes-or-no-p'
which doesn't TAB complete the user answer. Let's play safe and
keep requiring full answers.
* emacs-master/lisp/dired.el (dired-delete-file): Use `read-string'
instead of `completing-read' to read the user answers.
* lisp/dired.el (dired-delete-file): Accept 2 additional answers:
'all', to delete all directories recursively and no prompt anymore.
'quit', to cancel directory deletions (Bug#27940).
Show help message when user inputs 'help'.
(dired-do-flagged-delete): Bind locally dired-recursive-deletes
so that we can overwrite its global value.
Wrapp the loop within a catch '--delete-cancel to catch when
the user abort the directtry deletion.
* doc/emacs/dired.texi (Dired Deletion): Update manual.
* etc/NEWS (Changes in Specialized Modes and Packages in Emacs 26.1):
Announce this change.
* lisp/emacs-lisp/autoload.el (autoload--save-buffer):
* lisp/emacs-lisp/bytecomp.el (byte-compile-file):
Use make-temp-file, not make-temp-name, to avoid an unlikely race
that could lose data. Remove the deletion hook as quickly as
possible after the file is renamed; though a race still remains
here, it is smaller than before.
Positions might change if the length of one dired header line
changes; this happen, for instance, if we add new files.
Instead, line numbers are invariant under shrinks/enlargements
of the file header.
https://lists.gnu.org/archive/html/emacs-devel/2017-07/msg01092.html
* lisp/dired.el (dired-save-positions): Save the line numbers at point.
(dired-restore-positions): Use forward-line to restore the original
position (Bug#27968).
* test/lisp/dired-tests.el (dired-test-bug27968): Add test.
Respect comment-auto-fill-only-comments when auto-filling and a
comment syntax is defined.
* lisp/newcomment.el (comment-indent-new-line): Do not check
comment-auto-fill-only-comments.
* lisp/simple.el (internal-auto-fill): New defun.
* src/cmds.c (internal_self_insert): Call Qinternal_auto_fill, not
auto_fill_function.
(syms_of_cmds): Define Qinternal_auto_fill.
* lisp/ruler-mode.el (ruler-mode-ruler, ruler-mode-window-col):
* lisp/emacs-lisp/tabulated-list.el (tabulated-list-init-header)
(tabulated-list-print-entry): Account for the width taken by
line-number display. (Bug#27895)
* src/buffer.c (Fgenerate_new_buffer_name): Test IGNORE for being
nil before calling string-equal, since the latter will compare
"nil and 'nil' as equal. (Bug#27966)
* test/src/buffer-tests.el
(test-generate-new-buffer-name-bug27966): New test.
