This merges branch 'line-numbers'.
* src/buffer.c (disable_line_numbers_overlay_at_eob): New
function.
* src/lisp.h (disable_line_numbers_overlay_at_eob): Add prototype.

of line-number display is needed.

(syms_of_indent): Defsubr it.
* src/indent.c (Fvertical_motion): Help C-n/C-p estimate correctly
the width used up by line numbers by looking near the window-start
point. If window-start is outside of the accessible portion,
temporarily widen the buffer.
* src/term.c (produce_glyphs): Adjust tab stops for the horizontal
space taken by the line-number display.
* src/xdisp.c (display_count_lines_logically)
(display_count_lines_visually, maybe_produce_line_number)

optimizations as for relative.

Don't display line numbers in the minibuffer and in tooltip
frames.
Call row_text_area_empty to verify that a glyph
row's text area is devoid of any glyphs that came from a buffer or

(dns-mode-ipv6-to-nibbles, dns-mode-reverse-and-expand-ipv6):
New functions.
* test/lisp/dns-mode-tests.el: New file.
; * etc/NEWS: Mention this.
"%o" will display the percentage "travel" of the window through the buffer.
"%q" will display a combination of the percentage offsets of the top and
bottom of the window. The new user option mode-line-percent-position will
facilitate selecting a setting for this part of the mode line.
* lisp/bindings.el (mode-line-percent-position): New customizable user option.
(mode-line-position): Use mode-line-percent-position in place of "%p", etc.
* src/xdisp.c (decode_mode_spec): Add handlers for "%o" and "%q".
* doc/lispref/modes.texi (Mode Line Variables): Document
mode-line-percent-position.
(%-Constructs): Document %o and %q.
* etc/NEWS: Add an entry for these new facilities.
* lisp/frame.el (ns-set-mouse-absolute-pixel-position): New
function (Lisp).
(set-mouse-absolute-pixel-position): Change it to call
`ns-set-mouse-absolute-pixel-position' on macOS.
* src/nsfns.m (Fns_set_mouse_absolute_pixel_position): New
function.
* src/nsterm.h (NS_PARENT_WINDOW_TOP_POS): Use the primary
screen's height as a base for calculating global coordinates.
* src/nsterm.m (frame_set_mouse_pixel_position): Fix it in macOS.
* test/lisp/mouse-tests.el (bug26816-mouse-frame-movement): Test
movement of mouse relative to frame.
Instead of a lambda, create a new type containing all data required to
call the function, and support it in the evaluator. Because this type
now also needs to store the function documentation, it is too big for
Lisp_Misc; use a pseudovector instead. That also has the nice benefit
that we don't have to add special support to the garbage collector.
Since the new type is user-visible, give it a predicate.
Now we can easily support 'help-function-args' and 'func-arity'; add
unit tests for these.
* src/lisp.h (allocate_module_function, MODULE_FUNCTIONP)
(XMODULE_FUNCTION): New pseudovector type 'module function'.
* src/eval.c (FUNCTIONP): Also treat module functions as functions.
(funcall_lambda, Ffuncall, eval_sub): Add support for calling module
functions.
(Ffunc_arity): Add support for detecting the arity of module
functions.
* src/emacs-module.c (module_make_function): Adapt to new structure.
Return module function object directly instead of wrapping it in a
lambda; remove FIXME.
(funcall_module): New function to call module functions. Replaces
`internal--module-call' and is called directly from eval.c.
(syms_of_module): Remove internal helper function, which is no longer
needed.
(module_function_arity): New helper function.
* src/data.c (Ftype_of): Adapt to new implementation.
(Fmodule_function_p, syms_of_data): New user-visible function. Now
that module functions are first-class objects, they deserve a
predicate. Define it even if not compiled with --enable-modules so
that Lisp code doesn't have to check for the function's existence.
* src/doc.c (Fdocumentation): Support module functions.
* src/print.c (print_object): Adapt to new implementation.
* src/alloc.c (mark_object): Specialized garbage collector support is
no longer needed.
* lisp/help.el (help-function-arglist): Support module functions.
While there, simplify the arity calculation by using `func-arity',
which does the right thing for all kinds of functions.
* test/data/emacs-module/mod-test.c: Amend docstring so we can test
the argument list.
* test/src/emacs-module-tests.el (mod-test-sum-docstring): Adapt to
new docstring.
(mod-test-non-local-exit-signal-test): Because `internal--module-call'
is gone, the backtrace has changed and no longer leaks the
implementation.
(module--func-arity): New test for `func-arity'.
(module--help-function-arglist): New test for `help-function-arglist'.
* lisp/emacs-lisp/find-func.el (find-library-other-window)
(find-library-other-frame): New commands to complement the
existing 'find-library' command. (Bug#26712)
(read-library-name): New function to read a library name.
* etc/NEWS: Mention 'find-library-other-window' and
'find-library-other-frame'.
* lisp/simple.el (eval-expression-print-maximum-character): New
variable.
(eval-expression-print-format): Only display value as character if
it's less than or equal to `eval-expression-print-maximum-character'.
(eval-expression-get-print-arguments): Check
eval-expression-print-maximum-character, allow negative arg to
override it.
(eval-expression):
* lisp/progmodes/elisp-mode.el (elisp--eval-last-sexp):
(elisp--eval-last-sexp-print-value): Handle new variable.
* doc/emacs/building.texi (Lisp Eval): Document new variable and
behavior.
* etc/NEWS: Announce it.
* test/lisp/progmodes/elisp-mode-tests.el
(eval-last-sexp-print-format-small-int)
(eval-last-sexp-print-format-small-int-echo)
(eval-last-sexp-print-format-large-int)
(eval-last-sexp-print-format-large-int-echo):
* test/lisp/simple-tests.el (eval-expression-print-format-small-int)
(eval-expression-print-format-small-int-echo)
(eval-expression-print-format-large-int)
(eval-expression-print-format-large-int-echo): New tests.
* lib-src/emacsclient.c (main, decode_options)
(print_help_and_exit, longopts): New option '--tramp' / '-T' which
specifies how emacs should use tramp to find remote files.
* doc/emacs/misc.texi (TCP Emacs server): New subsection describing
the various knobs to tune server.el for TCP opereation.
(emacsclient Options): Reference "TCP Emacs server" from description of
--server-file. Document the new '--tramp' / '-T' options.
* doc/emacs/emacs.texi (Top): Update the top-level menu.
* etc/NEWS: Mention the new option.
