The functions make-process and make-network-process have many
keyword args and it's easy to misspell some of them.
Use a compiler macro to warn about some possible mistakes.
* lisp/emacs-lisp/bytecomp.el (bytecomp--check-keyword-args): New
helper.
(make-process, make-network-process): Define a compiler macro that
performs some checks but doesn't anything else.
* test/lisp/emacs-lisp/bytecomp-tests.el: Add some tests.
* test/lisp/emacs-lisp/bytecomp-resources/:
(warn-make-process-missing-keyword-arg.el,
warn-make-process-missing-keyword-value.el,
warn-make-process-repeated-keyword-arg.el,
warn-make-process-unknown-keyword-arg.el): New test files
* lisp/emacs-lisp/byte-opt.el (byte-optimize-equal, byte-optimize-eq):
Optimise (eq X X) -> t where X is a variable; idem for eql and equal.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add test case.
* lisp/emacs-lisp/lisp-mnt.el (lm-section-mark, lm-code-mark)
(lm-commentary-mark, lm-history-mark): Mark Emacs 21 compatibility
aliases obsolete. Update all callers to use the new name.
Before this fix, when 'byte-compile-ignore-files' was nil,
'byte-recompile-directory' would ignore every file (bug#64985).
* lisp/emacs-lisp/bytecomp.el (byte-recompile-directory): Handle case
when 'byte-compile-ignore-files' is nil.

This caused an issue where package-specific autoload cookies weren't
being correctly recognized, so they got dumped into the package's main
"<pkg>-autoloads.el" file, instead of "<pkg>-loaddefs.el" as they
should (bug#65023).
* lisp/emacs-lisp/loaddefs-gen.el (loaddefs-generate--parse-file):
Save match data when checking syntax.
* lisp/emacs-lisp/byte-opt.el (byte-after-unwind-ops):
Cease sinking `eq` past `unwind`, because that optimised away the
let-binding in
(let ((symbols-with-pos-enabled nil))
(eq x y))
and `eq` is currently sensitive to `symbols-with-pos-enabled`.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp--eq-symbols-with-pos-enabled): New test.

* lisp/emacs-lisp/rx.el:
Add tables of legacy syntax.
(rx--translate-symbol):
Translate the legacy construct `not-wordchar` as (not wordchar), which
is more intuitively obvious.
* lisp/emacs-lisp/rx.el (rx--translate-syntax):
Generate the shorter \w and \W instead of \sw and \Sw.
* test/lisp/emacs-lisp/rx-tests.el (rx-atoms, rx-syntax, rx-not):
Adapt tests.
* lisp/emacs-lisp/rx.el (rx--generate-alt):
Treat the intervals and classes lists separately without joining,
to reduce allocation. Handle special cases first.
(rx--union-intervals):
Implement directly instead of using intersection and complement.
* test/lisp/emacs-lisp/rx-tests.el (rx-any): Adapt test, as some
character alternatives are now slightly different.
(rx--complement-intervals, rx--union-intervals)
(rx--intersect-intervals): New unit tests.
* lisp/emacs-lisp/subr-x.el (string-pixel-width): Disable
'line-prefix' and 'wrap-prefix' to avoid their effect on the
calculated string width. (Bug#64971)
(rx (in (?^ . ?a))) was incorrectly translated to "[^-a]".
Change it so that we get "[_-a^]" instead.
* lisp/emacs-lisp/rx.el (rx--generate-alt): Split ranges starting with
`^` occurring first in a non-negated character alternative.
* test/lisp/emacs-lisp/rx-tests.el (rx-any): Add and adapt tests.
(cherry picked from commit 5f5d668ac7)
(rx (in (?^ . ?a))) was incorrectly translated to "[^-a]".
Change it so that we get "[_-a^]" instead.
* lisp/emacs-lisp/rx.el (rx--generate-alt): Split ranges starting with
`^` occurring first in a non-negated character alternative.
* test/lisp/emacs-lisp/rx-tests.el (rx-any): Add and adapt tests.
* lisp/emacs-lisp/map.el (map-let, map)
(map--make-pcase-bindings): Add a third argument for specifying a
default value, like in 'map-elt'. (Bug#49407)
* lisp/emacs-lisp/map.el (map--make-pcase-bindings): Clarify that keys
that aren't found aren't ignored, they actually get the value
nil (unless the new default value is given). The overall pattern can
still fail to match if the sub-pattern for the unfound key doesn't
match nil.
* test/lisp/emacs-lisp/map-tests.el (test-map-let-default)
(test-map-plist-pcase-default, test-map-pcase-matches): Add tests,
including for the above item.
Implement char-before, backward-char and backward-word as compiler
macros instead of byte-compile handlers so that the source-level
optimiser gets to simplify the result. In particular, this removes
some branches.
* lisp/emacs-lisp/bytecomp.el (byte-compile-char-before)
(byte-compile-backward-char, byte-compile-backward-word): Remove.
(bytecomp--char-before, bytecomp--backward-char)
(bytecomp--backward-word): New.
* lisp/emacs-lisp/byte-opt.el (byte-opt--nary-comparison):
Fix a typo causing miscompilation of code such as (OP X),
where OP is <, >, <=, >= or =.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-tests--test-cases): Add test case.
Reported by Richard Copley.
* lisp/emacs-lisp/lisp-mode.el (lisp-imenu-generic-expression):
Add defvar-keymap. We do not ignore (defvar-keymap FOO)
constructs in imenu as we do with (defvar FOO) since the former
constructs are generally not vacuous whereas the latter ones
often are. (Bug#64831)
When a macro expanded to a call to an obsolete macro, we failed
to emit a warning for that use of the obsolete macro.
* lisp/emacs-lisp/macroexp.el (macroexp-macroexpand):
Use `macroexpand-1` to check obsolecence of intermediate expansions.
* test/lisp/emacs-lisp/macroexp-tests.el
(macroexp--test-obsolete-macro): New test.
The Emacs regexp engine interprets character ranges from ASCII to raw
bytes, such as [a-\xfe], as not including non-ASCII Unicode at all;
ranges from non-ACII Unicode to raw bytes, such as [ü-\x91], are
ignored entirely.
To make rx produce a translation that works as intended, split ranges
that that go from ordinary characters to raw bytes. Such ranges may
appear from set manipulation and regexp optimisation.
* lisp/emacs-lisp/rx.el (rx--generate-alt): Split intervals that
straddle the char-raw boundary when rendering a string regexp from an
interval set.
* test/lisp/emacs-lisp/rx-tests.el (rx-char-any-raw-byte):
Add test cases.
