* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* m4/open-slash.m4: New file, copied from Gnulib.

* time-stamp-tests.el: Expand unit tests to cover all formatting options.
These tests validate time-stamp-pattern formatting that has existed
since at least Emacs 22 (released in 2007).  The tests cover both
documented behavior and behavior implemented to support future migrations.

* time-stamp.el (time-stamp-string): Add a second argument (TIME) to
open a testing seam.  Have the unit tests call this public function.

* time-stamp.el (time-stamp-string, time-stamp-string-preprocess):
Remove the second pass through time-string--format.  (Previously both
functions called it.)  It was used only to handle "%", but this is now
handled by having time-stamp-string-preprocess not double it.
Not doubling the "%" in time-stamp-string-preprocess fixes the padding
of "%2%", which was discovered by the new unit tests to be wrong.

* lisp/emacs-lisp/debug.el (debug): Mention that inhibit-redisplay
will inhibit the function.

* lisp/gnus/message.el (message-check-recipients): Warn about
invalid email addresses (bug#32639).

* doc/misc/gnus.texi (Posting Styles): Remove bit about
message-reply-headers, because it has never worked.

* lisp/gnus/gnus-win.el (gnus-use-atomic-windows): Default to nil.

* doc/misc/gnus.texi (Posting Styles): Update the type of the
message-reply-headers object.

* lisp/mail/mailclient.el (mailclient-send-it): Warn about trying
to send attachments (bug#34992).

* lisp/progmodes/js.el (js-syntax-propertize): Ignore comments and
strings.
* test/manual/indent/jsx-comment-string.jsx: New test.

The regexp in this list used a capitalized “React” because it actually
should be capitalized like that.  Otherwise, the following code would
produce a false positive match: import Thing from './react/Thing'

* lisp/progmodes/js.el (js-jsx-regexps): Update docstring.
(js-jsx--detect-and-enable): Match case-sensitively when determining
whether JSX should be enabled.

This is a followon fix for Bug#37477.
* lisp/simple.el (region-extract-function):
Use setq here, since the var is now defined in C code.
* src/casefiddle.c (casify_pnc_region): New function.
(Fupcase_region, Fdowncase_region, Fcapitalize_region)
(Fupcase_initials_region): Use it.
(Fupcase_initials_region): Add region-noncontiguous-p flag
for consistency with the others.  All uses changed.
(syms_of_casefiddle): Define Qbounds, Vregion_extract_function.
* src/insdel.c (prepare_to_modify_buffer_1):
* src/keyboard.c (command_loop_1):
Use Vregion_extraction_function.
* src/insdel.c (syms_of_insdel): No need to define
Qregion_extract_function.
* test/src/casefiddle-tests.el (casefiddle-oldfunc): New var.
(casefiddle-loopfunc, casefiddle-badfunc): New functions.
(casefiddle-invalid-region-extract-function): New test.

* doc/misc/gnus-faq.texi (FAQ 7-1):
* doc/misc/gnus.texi (Maildir):
* lisp/gnus/nnmaildir.el: qmail.org no longer exists.

* lisp/auth-source.el (authinfo--hide-passwords): Ensure that we
only hit actual "password" entries and not "foo-password" and the
like.

* doc/misc/gnus.texi (Window Layout): Use @pxref in parentheses.

* lisp/image-mode.el (image-toggle-display-image): Get the
orientation from the Exif data, if any.

* lisp/image/exif.el (exif-parse-buffer): New function.
(exif-orientation): Ditto.
(exif-error): New error symbol, and adjust all error signalling to
only use that signal.

* src/pdumper.c (dump_buffer): Update hash of struct buffer.

* lisp/gnus/gnus-win.el (gnus-use-atomic-windows): New boolean
  customization option.
  (gnus-configure-windows): When removing old window layouts, check
  for and remove atomicity.
  (gnus-configure-windows): When gnus-use-atomic-windows is non-nil,
  make Gnus window layouts atomic.
* doc/misc/gnus.texi (Window Layout): Document.

* lisp/simple.el (capitalize-dwim): Add arg region-noncontiguous-p
in capitalize-region call.

* src/casefiddle.c (Fcapitalize_region): Add arg region-noncontiguous-p.
If non-nil, operate on multiple chunks.  (Bug#37477)
(Fdowncase_region): Use builtin symbol Qregion_extract_function
rather than calling intern.

Continued fixes for a81223ae

* lisp/gnus/gnus-registry.el (gnus-registry-article-marks-to-names,
  gnus-registry-article-marks-to-chars): object-p is obsolete.

Problem reported by Andreas Schwab (Bug#37475).
* doc/lispref/files.texi (Writing to Files)
(Testing Accessibility, Kinds of Files):
Document that accessibility and file-type predicates return nil
if there is trouble determining accessibility or type.
* etc/NEWS: Adjust, and list the affected primitives.
* src/callproc.c (init_callproc): Go back to Ffile_exists_p.
* src/fileio.c (PICKY_EACCES, file_test_errno):
Remove.  All uses removed.
(Ffile_name_case_insensitive_p, Ffile_exists_p, Ffile_symlink_p)
(Ffile_directory_p, Ffile_regular_p): Document that these
functions return nil if there is trouble.
(Ffile_name_case_insensitive_p, check_file_access)
(Ffile_writable_p, Ffile_symlink_p, Ffile_directory_p)
(Ffile_accessible_directory_p, Ffile_regular_p)
* src/lread.c (Fload):
Go back to treating trouble in determining the answer as if the
file were missing.
* src/fileio.c (Ffile_newer_than_file_p): Use file_attribute_errno
not file_test_errno, since returning nil is not appropriate when
there are two files to test; e.g., in the rare cases where both
file timestamps have overflowed then neither t nor nil is correct.

Emacs' global indent-tabs-mode=nil setting (and much of the
indentation in these fails is already spaces anyway).  Also remove
tab-width=8 settings, since those are redundant with the setting in
the top-level .dir-locals.el.

* lisp/image/exif.el (exif--parse-exif-chunk)
(exif--parse-directory): Commentary typo fixes.

* lisp/image/exif.el: New file (bug#23070).

* lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1): Don't recognize the
construct in CASE 18, unless additionally at-decl-end is set.

and .netrc files.

* lisp/reveal.el (reveal-open-new-overlays): Allow also toggling

images, and what to do about that (bug#33275).

* src/process.c (Fmake_network_process): Mention how to listen to
all interfaces (bug#34617).

* lisp/gnus/gnus-registry.el (gnus-registry-article-marks-to-chars):
  (gnus-registry-article-marks-to-names): The registry is an object,
  not a hash table.

* lisp/gnus/message.el (message-encode-message-body): Pass in the
content type if the user has given one.

* lisp/gnus/mml.el (mml-parse-1): Remove bogus peek at
Content-type (there are no headers here)  (bug#36527).

* lisp/gnus/mml.el (mml-generate-mime): Respect that.
