* src/floatfns.c (double_integer_scale): Simplify, so that the
function works when (FP_ILOGBNAN == INT_MAX && FP_ILOGB0 == INT_MIN),
as on Solaris.

When using this option and editing input, some transient situations
may arise that lead to file-name shadowing, but that shouldn't
necessarily lead to auto-delete behaviour, which will be suprising.

In '/foo/x/bar', if the user deletes the 'x', shadowing occurs, but
probably shouldn't.  So, somewhat like ido-mode, only auto-tidy
shadowed file names if the user is inserting text at end of input.

* lisp/icomplete.el (icomplete-exhibit): Check this-command.
(icomplete-tidy-shadowed-file-names): Tweak docstring.

Fix initialization of `state`.
Special-case `qw(...)` because we do want to indent its contents.

This avoids running doc-view-mode on files that are actually text
files.

* lisp/files.el (auto-mode-alist): Don't use doc-view-mode-maybe
for .doc (but continue to do so for .docx).
(magic-fallback-mode-alist): Add signature for .doc files.

* doc/lispref/functions.texi (Function Documentation): Improve
indexing (bug#38158).

The old code assumed that hexdigit initialization (needed by
non-GCC) could be done in syms_of_character, but that is no longer
true with pdumper.  Instead, simplify hexdigit init so that it can
be done statically on all C99 platforms.  Problem discovered on
Solaris 10 sparc + Oracle Solaris Studio 12.6.
* src/character.c (hexdigit): Add 1 to every value; all uses
changed.  This simplifies the initialization so that it can be
done statically on any C99 compiler.  hexdigit is now always const.
(syms_of_character): Omit no-longer-necessary initialization.
* src/character.h (HEXDIGIT_CONST, HEXDIGIT_IS_CONST):
Remove.  All uses removed.

* doc/lispref/variables.texi (Watching Variables): Clarify the
documentation of 'add-variable-watcher' and fix markup.

* src/data.c (Fadd_variable_watcher): Clarify the doc string.
(Bug#38205)

* lisp/vc/vc-hg.el (vc-hg-retrieve-tag): Avoid using subr-x
function (bug#38216).

* lisp/dframe.el (dframe-frame-mode): Use 'set-window-buffer'
instead of 'switch-to-buffer’ to avoid that
'switch-to-buffer-obey-display-actions' butts in (Bug#37840).

* lisp/vc/vc-hg.el (vc-hg-retrieve-tag): Don't pass empty name to
`hg update` (bug#38216).

* lisp/isearch.el (isearch-forward): Doc string formatting fix
(bug#38207).

* lisp/emacs-lisp/edebug.el (edebug-remove-instrumentation):
Macros can also have edebug instrumentation, so remove that as
well (bug#38195).

* lisp/gnus/nnir.el (nnir-method-default-engines): Update version tag.

* src/xdisp.c (tty_handle_tab_bar_click): Revert the last
change which made this work only in the HAVE_NTGUI build.
This function is needed by any build which supports a  mouse
on TTY frames.

* src/floatfns.c (double_integer_scale): Distinguish Inf from NaN.
(rounding_driver): Handle (ceil 0 0.0) and (ceil 0 1.0e+INF).
* test/src/floatfns-tests.el (special-round): Add tests for
weird cases like this.

Avoid crash with (floor 0 0.0)
* src/floatfns.c (rounding_driver): Signal an arithmetic
error if divisor is 0.0 or -0.0, instead of crashing.

Also prefer setf over oset.
(semanticdb-abstract-table-list): Always define.
(semanticdb--inhibit-make-directory): Fix name of declaration to match
name of variable actually used.
(semanticdb-with-match-any-mode): Use `declare`.  Add Edebug spec.
(semanticdb-project-roots): Remove redundant :group.

Problem reported by Paul Pogonyshev (Bug#38191).
* src/editfns.c (styled_format): When checking for adjacent
%-sequences, use byte position rather than character position.
* test/src/editfns-tests.el (format-properties): Test for fix.

* src/font.c (fset_font_data, font_put_frame_data)
(font_get_frame_data):
* src/ftfont.c (ftfont_open, ftfont_close)
(ftfont_encode_char, ftfont_glyph_metrics)
(ftfont_text_extents, ftfont_driver):
Define only if USE_CAIRO.
* src/xdisp.c (tty_handle_tab_bar_click):
Define only if HAVE_NTGUI && !CYGWIN.

* lisp/reposition.el (repos-count-screen-lines): Narrow without
changing point-min.  It wasn't necessary for vertical-motion to
work, and it had some adverse effects on how font-lock rules were
applied
(https://lists.gnu.org/archive/html/emacs-devel/2019-11/msg00522.html).
This can also be an alternative fix for bug#38049.

This (along with a suggestion to the OP to set
open-paren-in-column-0-is-defun-start to nil) fixes bug #37910.  It may also
have fixed bug #5490 and bug #18072.

* lisp/progmodes/cc-engine.el (c-state-cache-non-literal-place): Remove thi
non-sensical function, replacing it with ....
(c-state-cache-lower-good-pos): New function.
(c-renarrow-state-cache, c-append-lower-brace-pair-to-state-cache)
(c-remove-stale-state-cache, c-remove-stale-state-cache-backwards): Instead of
altering the state-cache list structure with setcar and setcdr, use setq and
consing.
(c-parse-state-1): Call c-state-cache-lower-good-pos rather than
c-state-cache-non-literal-place.

* src/gtkutil.h: Remove unneeded prototype for font_is_ignored,
it's in font.h now.

* so-long.el (so-long-minor-modes): Add flymake-mode, flyspell-mode,
and flycheck-mode.

* so-long.el (so-long-version, so-long--latest-version): New variables.

This enables users to safely load version 1.0 of so-long.el on top of
an earlier version, as well as making provisions for doing likewise
following any incompatible changes arising in future versions.

* so-long.el (so-long-inhibit-whitespace-mode)
(so-long-make-buffer-read-only, so-long-revert-buffer-read-only)
(so-long-inhibit-global-hl-line-mode): Restore dummy definitions of
now-obsolete hook functions used by earlier versions of so-long.el,
to support users who have saved these symbols in their customized
values for the hooks in question.

This is for consistency with the other function options, which all
used the 'radio' custom type.

* lisp/so-long.el (so-long-invisible-buffer-function): New user option.
(so-long--set-auto-mode): Use so-long-invisible-buffer-function.
(so-long-deferred): New function/value for so-long-invisible-buffer-function.
(so-long, so-long--disable): Support for so-long-deferred.

* test/lisp/so-long-tests/autoload-longlines-mode-tests.el
* test/lisp/so-long-tests/autoload-major-mode-tests.el
* test/lisp/so-long-tests/autoload-minor-mode-tests.el
* test/lisp/so-long-tests/so-long-tests.el:
Support for so-long-deferred.

Pre-existing tests have been updated to ensure the buffer is already
displayed in cases where a call to `normal-mode' is the (potential)
trigger for `so-long'.

* lisp/so-long.el: Documentation fixes.  For the purposes of
consistency, this reverts some of the changes made in commit
41ba8231, including one which
had introduced inconsistent spelling.

ispell configuration and LocalWords have been added such that
`ispell-buffer' should find no misspellings for this library.

* test/lisp/so-long-tests/spelling-tests.el (so-long-spelling):
New test to check the spelling using `ispell-buffer'.

* doc/lispref/minibuf.texi (Multiple Queries): Move the
reference to 'read-char-from-minibuffer' from here...
* doc/lispref/commands.texi (Reading One Event): ...to here.
Fix the wording of the description of
'read-char-from-minibuffer'.

* src/font.c (font_delete_unmatched): Move Vface_ignored_fonts
matching to...
(font_is_ignored): ..Here.  New function.
* src/gtkutil.c (xg_font_filter): New function, uses font_is_ignored
to filter fonts.
(xg_get_font): Set GTK font chooser filter to xg_font_filter.
* src/gtkutil.h: Add prototype for font_is_ignored.

* lisp/mail/rfc2047.el
(rfc2047-quote-special-characters-in-quoted-strings): Make obsolete
instead of removing it.

* lisp/mail/rfc2047.el
(rfc2047-quote-special-characters-in-quoted-strings): Remove function.
(rfc2047-encode-message-header, rfc2047-encode-region): Don't use it.

* lisp/vc/vc.el (vc-default-update-on-retrieve-tag): Accept
backend argument (bug#38156).  This fixes a bug introduced in the
previous patch.

* lisp/gnus/gnus-art.el (gnus-article-add-button): Make mouse-1
work as required by mouse-1-click-follows-link (bug#38144).

* lisp/vc/vc.el (vc-default-update-on-retrieve-tag): New function.
(vc-retrieve-tag): Call `update-on-retrieve-tag' backend function
to determine if prompt for update buffers is needed; Include tag
name into the "Retrieving tag" message.
* lisp/vc/vc-git.el (vc-git-update-on-retrieve-tag):
* lisp/vc/vc-hg.el (vc-hg-update-on-retrieve-tag):
* lisp/vc/vc-svn.el (vc-svn-udate-on-retrieve-tag): New functions.
Buffers update prompt on `vc-retrieve-tag' is omitted (bug#38156).
