* lisp/help-fns.el (help-fns--insert-bindings): New function.
(help-fns--key-bindings): Split menu/key handling and output menu
bindings separately (bug#52870).
* doc/emacs/haiku.texi (Haiku Basics): Update documentation.
* src/haiku_support.cc (Highlight): Apply the hack used for
regular menus to the menu bar as well.
* src/haikumenu.c (digest_menu_items): Set help text on menu bar
if `tooltip-mode' is t and system tooltips are used.
(syms_of_haikumenu): New symbol `tooltip-mode'.
Fchar_syntax did not convert unibyte characters to multibyte when the
current buffer was unibyte, in contrast to `char-syntax` in
byte-compiled code (bug#53260).
* src/bytecode.c (exec_byte_code): Call out to Fchar_syntax;
the dynamic frequency is too low to justify inlining here, and it
did lead to implementations diverging.
* src/syntax.c (Fchar_syntax): Convert non-ASCII unibyte values to
multibyte.
* test/src/syntax-tests.el (syntax-char-syntax): New test.
* doc/misc/eshell.texi (Built-in commands): Expand on the
documentation of echo (bug#27361).
* lisp/eshell/em-basic.el (eshell-echo): Respect OUTPUT-NEWLINE even
when 'eshell-plain-echo-behavior' is non-nil.
(eshell/echo): Add "-N" option and recommend its use over "-n" in
Lisp-friendly echo.
(eshell/printnl): Simplify; 'eshell-stringify' is equivalent to
calling 'eshell-echo' here.
* lisp/menu-bar.el (menu-bar-file-menu): Make the undelete frame
mode option a toggle. (bug#53382)
Also enable some options that were disabled on NS, but should no
longer be since NS now supports the tab bar.
* lisp/international/textsec.el (textsec-domain-suspicious-p):
Ensure that we're not confusing the user if there's a directional
override in the string we're checking.
* lisp/gnus/gnus-art.el (article--check-suspicious-addresses): Be
more resilient to junk in headers. (But all this should be rewritten
eventually, because the entire process is way too convoluted.)
* src/image.c (x_create_xrender_picture):
(Fimage_transforms_p): Use `xrender_supported_p'.
* src/xterm.c (x_term_init): Query for XRender support and
extension versions.
* src/xterm.h (struct x_display_info): New fields
`xrender_supported_p', `xrender_major' and `xrender_minor'.
* lisp/emacs-lisp/bytecomp.el (byte-to-native-output-buffer-file):
Rename from `byte-to-native-output-file'.
(byte-write-target-file): Update.
(byte-compile-file): Write the temporary .elc only when not native
compiling.
(byte-compile-file): Kill the .elc buffer only when not native
compiling.
* lisp/emacs-lisp/comp.el (batch-byte+native-compile): Instead of just
renaming the temporary .elc make use of `byte-write-target-file' to
write it down and kill the temporary buffer.
* lisp/gnus/gnus-art.el (gnus-treat-suspicious-headers): New user
option.
(gnus-article-treat-suspicious-headers): New function.
(article-decode-encoded-words): Hook into the machinery to check
headers.
(article--check-suspicious-addresses): New function.
* lisp/international/textsec-check.el (textsec-propertize): New
function.
(textsec-check): Only check, don't alter STRING.
* lisp/international/textsec.el (textsec-url-suspicious-p): New
function.
* lisp/net/shr.el (shr-tag-a): Mark suspicious links.
* lisp/international/textsec.el (textsec-domain-suspicious-p):
Consider domain names that are whole-script confusables with ASCII
to be suspicious. (I think this is what the Unicode standard is
recommending, but I'm not 100% sure.)
* lisp/international/textsec.el
(textsec-email-address-suspicious-p): Made into its own function.
(textsec-email-suspicious-p): Use it and adjust doc strings.
* configure.ac: Require `xcb-aux' to be present before using
XCB.
* src/xfns.c (x_sync):
(x_create_tip_frame):
(Fx_show_tip): Port window related code to XCB.
* lisp/international/textsec.el (textsec-name-suspicious-p):
(textsec-domain-suspicious-p):
(textsec-local-address-suspicious-p):
(textsec-name-suspicious-p):
(textsec-suspicious-nonspacing-p):
(textsec-email-suspicious-p): Suspiciosness isn't only about
homoglyphs, so don't claim so in the doc strings.
