* lisp/net/sieve-mode.el (sieve-mode-indent-function): New function.
(sieve-mode): Don't inherit from C mode, because the syntax
doesn't really resemble C mode that much (except being curly braced).
The background of the 'child-frame-border' face instead of the
'internal-border' face now controls the color of child frames'
borders.
The 'child-frame-border-width' frame parameter is now used for the
width of child frames' borders instead of internal-border-width',
though we still fall back on using the latter if the former is not
set.
* doc/lispref/frames.texi (Frame Layout): Mention
'child-frame-border' and 'child-frame-border-width'.
(Layout Parameters): Mention 'child-frame-border-width'.
* etc/NEWS: Mention new face 'child-frame-border' and frame
parameter 'child-frame-border-width'.
* lisp/faces.el (child-frame-border): New face.
* src/dispextern.h (enum face_id): Add CHILD_FRAME_BORDER_FACE_ID.
* src/frame.c (Fframe_child_frame_border_width): New function.
(gui_report_frame_params): Add entry for Qchild_frame_border_width.
* src/frame.h (struct frame): New slot child_frame_border_width.
(FRAME_CHILD_FRAME_BORDER_WIDTH): New inlined function.
* src/nsfns.m (ns_set_child_frame_border_width): New function.
(Fx_create_frame): Handle Qchild_frame_border_width parameter.
(ns_frame_parm_handlers): Add ns_set_child_frame_border_width.
* src/nsterm.m (ns_clear_under_internal_border): Handle
CHILD_FRAME_BORDER_FACE_ID.
* src/w32fns.c (w32_clear_under_internal_border): Handle
CHILD_FRAME_BORDER_FACE_ID.
(w32_set_internal_border_width): New function.
(Fx_create_frame): Handle Qchild_frame_border_width parameter.
(w32_frame_parm_handlers): Add w32_set_child_frame_border_width.
* src/xfaces.c (lookup_basic_face, realize_basic_faces): Handle
CHILD_FRAME_BORDER_FACE_ID.
* src/xfns.c (x_set_child_frame_border_width): New function.
(Fx_create_frame): Handle Qchild_frame_border_width parameter.
(x_frame_parm_handlers): Add x_set_child_frame_border_width.
* src/xterm.c (x_clear_under_internal_border)
(x_after_update_window_line): Handle CHILD_FRAME_BORDER_FACE_ID.
* lisp/startup.el (keyboard-type): Make obsolete and lex-bound.
* admin/unidata/unidata-gen.el (unidata-gen-file)
(unidata-gen-charprop): Mark the generated files to use lexical binding.
* lisp/international/isearch-x.el: Use lexical-binding.
(junk-hist): Declare locally.
* lisp/international/iso-cvt.el:
* lisp/international/utf-7.el:
* lisp/international/robin.el:
* lisp/international/ogonek.el:
* lisp/international/latin1-disp.el:
* lisp/international/kkc.el:
* lisp/international/kinsoku.el:
* lisp/international/ja-dic-utl.el: Use lexical-binding.
* lisp/international/ja-dic-cnv.el: Use lexical-binding.
(skkdic-breakup-string): Remove unused var `kana-len`.
* lisp/international/latexenc.el: Use lexical-binding.
(tex-start-of-header): Declare.
* lisp/international/mule-diag.el: Use lexical-binding.
(list-character-sets): Remove unused var `pos`.
(list-character-sets-1): Remove unused vars `tail` and `charset`.
(list-charset-chars): Remove unused vars `chars` and `plane`.
(describe-coding-system): Remove unused var `extra-spec`.
(mule--print-opened): New var.
(print-fontset): Bind it.
(print-fontset-element): Use it instead of `print-opened`.
* lisp/international/quail.el: Use lexical-binding.
(quail-start-translation, quail-start-conversion):
Remove unused var `generated-events`.
(quail-help-insert-keymap-description): Use local dynbound var `the-keymap`.
* lisp/files.el (dir-locals-collect-variables): Compare directory
names after expanding. This makes a (subdirs . nil) in ~/ work as
expected (bug#17205).
Test case:
((nil . ((a . "hallo")
(subdirs . nil))))
in ~/
* lisp/emacs-lisp/lisp-mode.el (lisp--el-match-keyword): Handle
special forms and macros the same way (bug#43265). This makes
things like (setq a '(if a b)) be fontified correctly (i.e., not
fontified as a keyword).
* lisp/emacs-lisp/lisp-mode.el (lisp--el-funcall-position-p):
Rename and rewrite to return the inverse value. Non-inverted
predicate functions are easier to reason about.
(lisp--el-non-funcall-position-p): Make obsolete.
* lisp/net/tramp-sh.el (tramp-sh-handle-insert-directory):
Use `tramp-sh--quoting-style-options'.
* test/lisp/net/tramp-tests.el (tramp--test-hpux-p, tramp--test-ksh-p):
Remove superfluous nil.
(tramp--test-sh-no-ls--dired-p): New defun.
(tramp--test-special-characters): Use it.
* lisp/gnus/gnus-start.el (gnus-subscribe-newsgroup): This was a
misunderstanding of the next/previous argument: no group should ever
be inserted before "dummy.group".
(gnus-group-change-level): Make it clearer that PREVIOUS can be
nil. In fact none of this code would error on a nil value, but it
_looks_ like nil is unexpected.
* test/src/process-tests.el (process-tests/multiple-threads-waiting):
Also check that 'thread-join' and 'thread-last-error' return the
expected errors.
* lisp/progmodes/xref.el (xref-revert-buffer):
Erase the buffer only after fetching the new contents (bug#46042).
(cherry picked from commit 5821dee094)

* test/lisp/autorevert-tests.el
(auto-revert-test07-auto-revert-several-buffers):
* test/lisp/emacs-lisp/seq-tests.el (test-seq-do-indexed)
(test-seq-random-elt-take-all): Fix errors from using add-to-list on
lexical variables.
* test/lisp/emacs-lisp/cl-lib-tests.el
(cl-lib-defstruct-record): Expect test to succeed when byte-compiled
following change of 2021-01-23 'Fix missing file&line info in
"Unknown defun property" warnings'.
(cl-lib-tests--dummy-function): Remove; no longer needed.
(old-struct): Silence byte-compiler warning about unused lexical
variable.
* lisp/files.el (dir-locals-collect-variables): Don't
destructively modify the cached structure (bug#17205), because
that means that (subdirs . nil) doesn't work.
* lisp/emacs-lisp/byte-run.el (defmacro, defun): Use
`macroexp--warn-and-return` rather than `message`.
* lisp/emacs-lisp/macroexp.el: Fix `macroexp--compiling-p`.
(macroexp--warn-and-return): Don't try and detect repetition on forms
like `nil`.
(macroexp-macroexpand): Don't forget to bind `macroexpand-all-environment`.
* lisp/hl-line.el (hl-line-mode, global-hl-line-mode): Ensure
that 'maybe-unhighlight' is called after line is highlighted.
(Bug#45946)
(hl-line-unhighlight, global-hl-line-unhighlight): Set overlay
variable to nil after overlay is deleted.
This unit test tests that we can call 'accept-process-output' in
parallel from multiple threads.
* test/src/process-tests.el (process-tests/multiple-threads-waiting):
New unit test.
While no deadlocks caused by the blocking write end have been reported
yet, marking both ends nonblocking is consistent and also recommended
in the GNU/Linux manpage of 'select'.
* src/process.c (child_signal_init): Mark write end of self-pipe as
nonblocking.
* doc/lispref/text.texi (Undo): Add a cross-reference to the
description of 'undo-amalgamate-change-group'.
(Atomic Changes): Expand and improve the description of
'undo-amalgamate-change-group'. (Bug#42303)
With `electric-indent-mode` enabled, `newline-and-indent` ends up indenting
3 times: once for the original line and twice on the new line.
`reindent-then-newline-and-indent` is even worse, indenting twice
both lines.
None of those commands should be affected by `electric-indent-mode`
since they even explicitly say in their name when and how they do
indentation.
(reindent-then-newline-and-indent): Temporarily disable
`electric-indent-mode` as well.
