The current syntax for functions in `app` and `pred` patterns
allows a shorthand (F ARGS) where the object being matched is
added as an extra last argument. This is nice for things like
(pred (< 5)) but sometimes the object needs to be at
another position.
Until now you had to use (pred (lambda (x) (memq x my-list)))
or (pred (pcase--flip memq my-list)) in those cases.
So, introduce a new shorthand where `_` can be used to indicate
where the object should be passed: (pred (memq _ my-list))

Monitors are wider now than when these defaults were first set, and it
is useful to take better advantage of that, to fit text on fewer lines.
Yet, it has repeatedly been shown that overly long lines reduce
readability:
"A reasonable guideline would be 55 to 75 characters per line."[1]
We also don't want to disfavor narrow displays, like mobile phones; a
more promising direction here might be to automatically word wrap
docstrings and make their maximum width customizable. That might
require a new docstring format, however.
Bumping it by 7 characters, from 65 to 72, seems a reasonable compromise
for now. Consideration was given to increasing it to 70 or 75, but 72
happens to be a commonly recommended maximum line width elsewhere (see
Fortran 66, Python docstrings, commit message recommendations, etc.),
and we might as well do the same.

The obsolete lazy-loaded bytecode feature, enabled by
`byte-compile-dynamic`, slows down Lisp execution even when not in use
because every call to a bytecode function has to check that function
for laziness.
This change forces up-front loading of all lazy bytecode so that we
can remove all those checks. (Dynamically loaded doc strings are not
affected.)
There is no point in generating lazy bytecode any more so we stop
doing that; this simplifies the compiler. `byte-compile-dynamic` now
has no effect.
This is a fully compatible change; the few remaining users of
`byte-compile-dynamic` should not notice any difference.

lazy bytecode.
* src/bytecode.c (exec_byte_code): Remove lazy bytecode checks.

Sometimes people may need to bisect to find specific revision
in a grammar library's repo. In this case they'd want to point
the URL to the local repo to avoid cloning it on every rebuild.
So add support for a directory instead of URL in
'treesit-language-source-alist'.
* lisp/treesit.el (treesit--install-language-grammar-1): Test
if URL is a local directory. Then if it is, avoid cloning the
repo and removing the path on success.
(treesit--git-clone-repo): Factor out the code for cloning to
a separate function.
(treesit--git-checkout-branch): A helper to checkout the
revision for cases where we didn't clone the repo but want it
to point the revision. (Bug#68579)
* src/w32fns.c (globals_of_w32fns) <w32-follow-system-dark-mode>:
New variable.

'w32-follow-system-dark-mode' is nil.
* etc/NEWS:

'w32-follow-system-dark-mode'.
Fractions of the form 123⁄456 are handled as if written 123:456. Note
in particular the difference in behavior from U+2215 DIVISION SLASH
and U+002F SOLIDUS, which result in division rather than a rational
fraction.

When set to 'insist', exit minibuffer with same key as
register name, instead of pressing RET. E.g., pressing
"a" selects register "a", then pressing "a" again exits

* etc/NEWS:

and indexing of 'visual-wrap-prefix-mode'.
* src/w32fns.c (DEFAULT_IMAGE_BASE): Define for 64-bit and 32-bit
MinGW builds.
(emacs_abort): Correct the callstack addresses for potential
relocation of the image base due to ASLR. This makes 'addr2line'
be able to interpret emacs_backtrace.txt when ASLR is in effect,
which it is on every modern version of MS-Windows. (Bug#63365)

slots.
(erc--input-split): Move `refoldp' to "superclass".
* lisp/erc/erc-goodies.el (erc--command-indicator-permit-insertion):
Use `substxt' field instead of overloading `insertp'.
(erc--command-indicator-display): Accept extra lines for
compatibility.
* lisp/erc/erc.el (erc-pre-send-functions): Revise doc.
(erc--input-ensure-hook-context, erc-input-refoldp): Remove unused
functions, originally meant to be new in ERC 5.6.
(erc--run-send-hooks): Copy data from additional fields of `erc-input'
object to `erc--input-split' workspace object.
(erc--send-input-lines): Handle `substxt' field of `erc-input' object
when it's non-nil. (Bug#68265)

`erc-insert-modify-hook' at depth -50.

hook-depth range in doc string.
The `mouse-wheel-DIR-event` vars were introduced because under X11
we get different `mouse-N` events depending on the users' mouse and
those same events can be used for other things for other rodents, so we
can't unconditionally treat those events as mouse-wheel events.
But this does not apply to the `wheel-up/down/...` events.
So hard code them.
* lisp/mwheel.el (mwheel--is-dir-p): Always consider the `wheel-DIR` events.
(mouse-wheel--setup-bindings): Always bind the `wheel-DIR` events.
* lisp/completion-preview.el (completion-preview--mouse-map):
Unconditionally bind the `wheel-DIR` events.
* lisp/edmacro.el (edmacro-fix-menu-commands): Hard code the
`wheel-DIR` events as mouse events regardless of `mouse-wheel-*-event`s.
* lisp/progmodes/flymake.el (flymake--mode-line-counter-map):
Do nothing, because it's already been done in commit e5be6c7ae3.
* doc/lispref/commands.texi (Misc Events): Document the need to use
`wheel-up/down/left/right` unconditionally.
* etc/tutorials/TUTORIAL.pl: Update text about scroll bar. New
text by Christopher Yeleighton <giecrilj@stegny.2a.pl>.
