* lisp/dired.el (dired): Use pop-to-buffer-same-window instead
of switch-to-buffer. This preserves Dired window point when
dired-auto-revert-buffer is non-nil. (Bug#27243)
* test/lisp/dired-tests.el (dired-test-bug27243): New test.
* lisp/ls-lisp.el (ls-lisp-filesize-d-fmt, ls-lisp-filesize-f-fmt)
(ls-lisp-filesize-b-fmt): Add space in front (Bug#27693).
* test/lisp/dired-tests.el (dired-test-bug27693): Add test.
* lisp/emacs-lisp/bytecomp.el (byte-compile--function-signature): New fun.
Dig into advice wrappers to find the "real" signature.
(byte-compile-callargs-warn, byte-compile-arglist-warn): Use it.
(byte-compile-arglist-signature): Don't bother with "new-style" arglists,
since bytecode functions are now handled in byte-compile--function-signature.
* lisp/files.el (create-file-buffer, insert-directory):
Remove workaround introduced for (bug#14860).
* lisp/help-fns.el (help-fns--analyse-function): `nadvice` is preloaded.
* lisp/help.el (help-function-arglist):
Dig into advice wrappers to find the "real" signature.
This fontification anomaly happened because after deleting the ">",
c-forward-<>-arglist parses the preceding identifier as a putative type but
stores it in c-found-types before it becomes clear it is not an unambiguous
type. c-forward-<>-arglist fails, leaving the spurious type id in
c-found-types. Fix this by "binding" c-found-types "to itself" in
c-forward-<>-arglist, and restoring the original value when that function call
fails.
* lisp/progmodes/cc-engine.el (c-copy-found-types): New function.
(c-forward-<>-arglist): Record the original value of c-found-types at the
beginning of the function, and restore it at the end on failure.
* lisp/progmodes/cc-mode.el (c-unfind-coalesced-tokens): Rewrite more
accurately.
* lisp/ses.el (ses-relocate-all): In case of insertion, do not
relocate value for named cells as they keep the same symbol.
(ses-rename-cell): Set new cell name symbol to cell value --- do not
rely on recalculating. Push cells with updated data --- cell name,
cell reference list, or cell formula --- to deferred write list.
* test/lisp/ses-tests.el: New file, with 7 tests for SES.
* lisp/progmodes/cc-defs.el (c-set-keymap-parent): New macro.
* lisp/progmodes/cc-mode.el (top-level): Remove cc-bytecomp-defun for
set-keymap-parents.
(c-make-inherited-keymap): Use c-set-keymap-parent in place of inline code.
* lisp/faces.el (line-number): Use a fixed-pitch font by default,
even if the default face uses a variable-pitch font. Reported by
James Cloos <cloos@jhcloos.com>.
* doc/misc/tramp.texi: Use consequently "@value{tramp}" and
"MS Windows".
(Quick Start Guide): New node.
* doc/misc/trampver.texi:
* lisp/net/trampver.el: Change version to "2.3.3-pre".
Without this fix, (substitute-object-in-subtree #0=(#0# 'a) 'a)
would dump core, since the C code would recurse indefinitely through
the infinite structure. This patch adds an argument to the function,
and renames it to lread--substitute-object-in-subtree as the function
is not general-purpose and should not be relied on by outside code.
See Bug#23660.
* src/intervals.c (traverse_intervals_noorder): ARG is now void *,
not Lisp_Object, so that callers need not cons unnecessarily.
All callers changed. Also, remove related #if-0 code that was
“temporary” in the early 1990s and has not been compilable for
some time.
* src/lread.c (struct subst): New type, for substitution closure data.
(seen_list): Remove this static var, as this info is now part of
struct subst. All uses removed.
(Flread__substitute_object_in_subtree): Rename from
Fsubstitute_object_in_subtree, and give it a 3rd arg so that it
doesn’t dump core when called from the top level with an
already-cyclic structure. All callers changed.
(SUBSTITUTE): Remove. All callers expanded and then simplified.
(substitute_object_recurse): Take a single argument SUBST rather
than a pair OBJECT and PLACEHOLDER, so that its address can be
passed around as part of a closure; this avoids the need for an
AUTO_CONS call. All callers changed. If the COMPLETED component
is t, treat every subobject as potentially circular.
(substitute_in_interval): Take a struct subst * rather than a
Lisp_Object, for the closure data. All callers changed.
* test/src/lread-tests.el (lread-lread--substitute-object-in-subtree):
New test, to check that the core dump does not reoccur.
Markdown sets both 'comment-start' and 'comment-use-syntax' to non-nil
values. Therefore 'electric-quote-mode' recognized it as a
programming mode. Fix this by first checking whether the current
major mode is derived from 'text-mode'.
* lisp/electric.el (electric-quote-post-self-insert-function): Treat
'text-mode' as stronger signal than comment syntax.
* test/lisp/electric-tests.el (electric-quote-markdown-in-text)
(electric-quote-markdown-in-code): Adapt unit tests.
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.
* src/dispextern.h (struct it): New members pt_lnum, lnum,
lnum_bytepos, lnum_width, and lnum_pixel_width.
* src/indent.c (line_number_display_width): New function,
refactored from line-number width calculations in vertical-motion.
(Fvertical_motion): Call line_number_display_width when the width
of line-number display is needed.
(Fline_number_display_width): New defun.
(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)
(should_produce_line_number, row_text_area_empty): New functions.
(try_window_reusing_current_matrix): Don't use this method when
display-line-numbers is in effect.
(try_window_id, try_cursor_movement): Disable these optimizations
when the line-number-current-line face is different from
line-number face and for relative line numbers.
(try_window_id, redisplay_window, try_cursor_movement): For
visual line-number display, disable the same redisplay
optimizations as for relative.
(x_produce_glyphs): Adjust tab stops for the horizontal
space taken by the line-number display.
(hscroll_window_tree): Adjust hscroll calculations to line-number
display.
(DISP_INFINITY): Renamed from INFINITY to avoid clashes with
math.h; all users changed.
(set_cursor_from_row): Fix calculation of cursor X coordinate in
R2L rows with display-produced glyphs at the beginning.
(display_line): Use should_produce_line_number to determine
whether a line number should be produced for each glyph row, and
maybe_produce_line_number to produce line numbers.
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
a string. This fixes a bug with empty-lines indication
disappearing when line numbers or line-prefix are displayed.

(todo-toggle-item-header): Use it. Make this command a noop
if the file has no items.
(todo-move-item, todo-item-done): Instead of concatenating the
items to move into one string, make a list of them to
facilitate handling hidden headers. Adjust insertion accordingly.

todo-raise-item-priority or todo-lower-item-priority when
point is on a done todo item or an empty line.

correctly handle deleting the now moved items from the source
category (without markers an infinite loop arises when moving
marked item to a preceding category).
(todo-unarchive-items): Put point on the (first) restored done
item, instead of leaving it at the end of the done items
separator string.
(todo-revert-buffer): Ensure buffer remains read-only after
reverting.

of line-number display is needed.

counts line numbers disregarding narrowing. Suggested by Andy

instead of display_count_lines. Adapt BEGV, ZV, etc. to
display-line-numbers-widen.

variable.

line's code ends in open paren, set comment indentation exactly to
column following it.

`lisp-comment-indent'.
* lisp/newcomment.el (comment-choose-indent): Interpret a cons of two
integers as indicating a range of acceptable indentation.
