* doc/misc/efaq.texi (No Escape key):
* doc/emacs/msdos-xtra.texi (MS-DOS Keyboard): Change back to
function-key-map from local-function-key-map, because these
bindings apply to all terminals.
* doc/lispref/keymaps.texi (Translation Keymaps): Clarify in what
circumstances you may still want to use function-key-map.
Derived from Ken Brown’s patch (Bug#36502#97).
* doc/lispref/files.texi (Relative File Names):
* etc/NEWS: Document this.
* src/fileio.c (user_homedir): New function.
(Fexpand_file_name, file_name_absolute_p): Use it.
(search_embedded_absfilename): Simplify via file_name_absolute_p.
* test/src/fileio-tests.el (fileio-tests--no-such-user): New test.
* lisp/gnus/gnus-sum.el (gnus-collect-urls-primary-text): Add defcustom.
(gnus-collect-urls): Use it.
(gnus-summary-browse-url): Mention it in the docstring.
* admin/merge-gnulib (GNULIB_MODULES): Add double-slash-root.
Emacs was already using this Gnulib module indirectly, so this
is merely noting that there is now a direct dependency.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* src/fileio.c (search_embedded_absfilename):
Use DOUBLE_SLASH_IS_DISTINCT_ROOT instead of (WINDOWSNT || CYGWIN).
Simplify.
* doc/misc/edt.texi (Changes):
* doc/emacs/custom.texi (Terminal Init): Use input-decode-map
instead of local-function-key-map, according to Stefan Monnier.
* lisp/filenotify.el (file-notify--rename): New defstruct.
(file-notify--pending-rename): Changed type.
(file-notify--handle-event): Adapt to new type.
Split callback code into backend-specific and general parts. Refactor
pending event, which is always a rename, to include relevant
information only. General clean-up.
* lisp/filenotify.el (file-notify--pending-event): Rename.
(file-notify--event-watched-file, file-notify--event-file-name)
(file-notify--event-file1-name, file-notify--event-cookie): Remove.
(file-notify--rename, file-notify--expand-file-name)
(file-notify--callback-inotify, file-notify--callback-kqueue)
(file-notify--callback-w32notify, file-notify--callback-gfilenotify)
(file-notify--call-handler, file-notify--handle-event): New.
(file-notify-callback): Split general parts into
file-notify--call-handler and file-notify--handle-event.

(file-notify--add-watch-gfilenotify): Use new callbacks.
* test/lisp/filenotify-tests.el
(file-notify--test-file, file-notify--test-add-watch): New.
(file-notify--test-event-test, file-notify--test-event-handler)
(file-notify-test02-rm-watch, file-notify-test03-events)
(file-notify-test05-file-validity, file-notify-test07-many-events)
(file-notify-test08-backup, file-notify-test09-watched-file-in-watched-dir):
Avoid using the internal `file-notify--event-watched-file' so that it
can be removed from filenotify.el.
Instead, pass the file name to the callback as an extra argument;
use `file-notify--test-add-watch' instead of `file-notify-add-watch'.
* test/lisp/filenotify-tests.el (file-notify--test-event-file)
(file-notify--test-event-file1, file-notify--test-event-test)
(file-notify--test-event-handler):
Define accessors locally, so that they can be removed from filenotify.el.
* doc/emacs/search.texi (Lax Search): Document
char-fold-symmetric, char-fold-include, char-fold-exclude.
* lisp/char-fold.el (char-fold--default-include)
(char-fold--default-exclude, char-fold--default-symmetric)
(char-fold--previous): New defconsts.
(char-fold-include, char-fold-exclude, char-fold-symmetric):
New defcustoms.
(char-fold-make-table): Use them.
(char-fold-update-table): New function called at top-level.

(char-fold--test-with-customization): New tests.
* src/alloc.c (c_symbol_p): Move from here ...
* src/lisp.h (c_symbol_p): ... to here, and make it more portable
to hypothetical platforms where pointers are wider than ptrdiff_t.
* src/pdumper.c (dump_builtin_symbol_p): Use c_symbol_p.
* lisp/progmodes/compile.el (compilation-goto-in-progress-buffer):
New command.
(compilation-in-progress): Don't put the in-progress mode-line
marker among the minor modes (because it's not a minor mode), and
add a command that allows you to switch to the in-progress
compilation buffer (bug#27252).
* lisp/char-fold.el (char-fold-make-table): Decompose the
decomposition of each character, adding equivalences to the original
character, until no more decompositions are left.
* doc/misc/viper.texi (Key Bindings):
* doc/misc/efaq.texi (X key translations for Emacs)
(No Escape key):
* doc/misc/edt.texi (Changes):
* doc/emacs/msdos-xtra.texi (MS-DOS Keyboard):
* doc/emacs/custom.texi (Terminal Init): Refer to
local-function-key-map instead of function-key-map, since the
latter isn't supposed to be changed (bug#27490).
Say that pdumping cannot redump unless -batch is used. Say that
the traditional unexec dumping method is by default not available,
and is deprecated. Don't call dump files "portable", as dump files
are not any more portable than the Emacs executables themselves.
Just call them "dump files". Similar, prefer "portable dumper"
(since the dumper code is portable) to "portable dumping" (since
the dump file is not). Be more systematic about calling them
"dump files" instead of "dumped images" or whatnot.
* lisp/progmodes/cc-engine.el (c-full-lit-near-cache): Amend the definition
such that an element's END element will be nil if the pertinent literal is
open at EOB.
(c-full-pp-to-literal): Before setting the aforementioned END element, check
that we're no longer in a literal. (c-literal-limits): When
c-full-pp-to-literal returns a list with a nil END element, replace this by
(point-max) to keep the interface of c-literal-limits unchanged.
* lisp/progmodes/cc-mode.el (c-after-change-mark-abnormal-strings): Having
found a string quote, check it is not inside an unterminated comment (i.e. one
at EOB).
* doc/lispref/strings.texi (Formatting Strings): Document this.
* src/editfns.c (styled_format): Support %o, %x, and %X on
finite floats less than zero or greater than UINTMAX_MAX.
* test/src/editfns-tests.el (format-%x-large-float)
(read-large-integer, format-%o-negative-float):
Adjust tests to match extended behavior.
Rename the latter test from format-%o-invalid-float,
since the float is no longer invalid.
* test/src/editfns-tests.el (format-%x-large-float)
(read-large-integer): Test this.
Following a suggestion by Stefan Monnier in:
https://lists.gnu.org/r/emacs-devel/2019-07/msg00530.html
* doc/lispref/hash.texi (Creating Hash, Defining Hash):
* src/fns.c (Fsxhash_eq, Fsxhash_eql, Fsxhash_equal, Fmake_hash_table):
Don’t insist that hash codes be fixnums, reverting
the recent doc changes to the contrary.
* src/bytecode.c (exec_byte_code): Special-case only the eq case,
as the others aren’t worth tuning now that we treat bignum hashes
like fixnums.

reduce its hash down to a fixnum.
* src/pdumper.c (dump_hash_table_stable_p):

(opascal-corrected-indentation): Presume we're already at first token.
(opascal-indent-line): Use indent-line-to.
(opascal-new-comment-line): Declare obsolete.
(opascal-mode-map): Keep the default M-j binding instead.

(resize_frame_windows): Drop fourth argument PIXELWISE - SIZE
is always specified in terms of pixels. Try to handle height
of mini windows more accurately.
(grow_mini_window, shrink_mini_window): Use body height of
mini window when calculating expected height change. Take
horizontal scroll bars into account.
(struct saved_window): Two new members to handle persistence
of window fringes and scroll bars.

persistence of fringes and scroll bars.
(set_window_fringes, set_window_scroll_bars): New arguments
PERSISTENT. Make dimension checks more accurate.
(Fset_window_fringes): New argument PERSISTENT.
(Fwindow_fringes, Fwindow_scroll_bars): Add PERSISTENT to
return values.
(Fset_window_scroll_bars): New argument PERSISTENT. In

Problem reported by Pip Cet in:
https://lists.gnu.org/r/emacs-devel/2019-07/msg00520.html
* src/alloc.c (inhibit_garbage_collection): Use new function.
(allow_garbage_collection): Accept intmax_t, not pointer.
* src/eval.c (default_toplevel_binding, do_one_unbind)
(backtrace_eval_unrewind, Fbacktrace__locals, mark_specpdl):
Support SPECPDL_UNWIND_INTMAX.
(record_unwind_protect_excursion): New function.
* src/lisp.h (enum specbind_tag): New constant SPECPDL_UNWIND_INTMAX.
(union specbinding): New member unwind_intmax.
* src/alloc.c (allow_garbage_collection)
(inhibit_garbage_collection): Temporarily bump
consing_until_gc, to improve performance of maybe_gc while
garbage collection is inhibited. Suggested by Stefan Monnier in:
https://lists.gnu.org/r/emacs-devel/2019-07/msg00511.html
* src/fns.c (INDEX_SIZE_BOUND): Use a tighter bound.
(maybe_resize_hash_table): Avoid integer overflow when
checking for hash table size overflow. Fix confusion
between INDEX_SIZE_BOUND (which is for the index vector)
and hash table size. Fix typo in debugging message
when ENABLE_CHECKING.
* doc/lispref/hash.texi (Creating Hash, Defining Hash):
* src/fns.c (Fsxhash_eq, Fsxhash_eql, Fsxhash_equal):
Say that hashes are fixnums.
(Fmake_hash_table): Say that that an integer rehash-size
should be a fixnum.
* doc/lispref/hash.texi (Defining Hash): Say that hash and
comparison functions should be consistent and pure, and should
return quickly.
* src/alloc.c (pure_alloc): Clear any heap-allocated storage.
This is simpler than auditing all the callers to make sure
they don’t assume pure memory is cleared memory, and the
performance implication is nonexistent except when Emacs
is misconfigured. Also, add an assertion to catch
caller misuse when pure space is exhausted.
