The composite DisplayDevice is meant to be presented to the user
only if it IsPresent. It is not entirely clear whether PowerSupply
implies IsPresent, so check both (bug#80229).
* lisp/battery.el (battery-upower): Skip hot-removable batteries
that are missing from the bay.
Now that battery--upower-subscribe registers to signals from
DisplayDevice (bug#80229), it is possible to react to more than just
State changes, including Percentage and IsPresent (although the
latter may already be covered by the DeviceAdded and DeviceRemoved
signals).
That means that it should be possible to disable polling via
battery-update-timer and still get timely mode line updates.
* etc/NEWS
(Changes in Specialized Modes and Packages in Emacs 31.1):
Announce new battery-update-interval :type.
* lisp/battery.el (battery-update-interval): Allow setting to nil.
(display-battery-mode): Do not create battery-update-timer then.
(battery-upower-display-device-path): New constant.
(battery--upower-subscribe): Use it.
(battery-upower-subscribe-properties): New variable.
(battery--upower-props-changed): Use it for more flexibility over
which DisplayDevice properties to react to.
(battery--upower-signal-handler): Call battery-update-handler
directly when there is no battery-update-timer.
* lisp/battery.el (battery--upower-props-changed): Check if the
"State" has changed.
(battery--upower-subscribe): Subscribe to state changes of the
"DisplayDevice" (bug#80229).
* src/lisp.h (struct Lisp_Fwd): With the predicate enum, we can now pack
the offset and the predicate into a one-word struct.
(XBUFFER_OFFSET): Use the new field name.
* src/buffer.c (DEFVAR_PER_BUFFER): Create the one-word struct.
* src/data.c (store_symval_forwarding): Use the new field name.
Using an enum instead of a symbol makes it obvious that this field is
of no concern to the GC.
* src/lisp.h (enum Lisp_Fwd_Predicate): New.
(struct Lisp_Fwd): Use it instead of a symbol.
* src/buffer.c (DEFVAR_PER_BUFFER): Create the necessary enum constant
instead of a symbol.

(store_symval_forwarding): Use it.
* src/lisp.h (struct Lisp_Buffer_Objfwd): Deleted.
(struct Lisp_Fwd): Add the fields bufoffset and bufpredicate.
Make the type a 1-byte bitfield so that the entire struct still
fits in two words.
(XBUFFER_OFFSET): Renamed from XBUFFER_OBJFWD.
* src/buffer.c (DEFVAR_PER_BUFFER, defvar_per_buffer)
(buffer_local_value): Update accordingly.

XBUFFER_OFFSET.

(struct Lisp_Fwd): ... replaced with field kbdoffset.
(DEFVAR_KBOARD): Use new field.
* src/data.c (XKBOARD_OFFSET): Renamed from XKBOARD_OBJFWD.

It was a struct with a single field.

(DEFVAR_INT): Update accordingly.
* src/data.c (XINTVAR): Updated and renamed from XFIXNUMFWD.
(do_symval_forwarding, store_symval_forwarding): Use it.
This contains the type and an union of Lisp_Objfwd, Lisp_Intfwd etc.
lispfwd is now a pointer to a struct Lisp_Fwd; the void *fwdptr field is
gone.
* src/lisp.h (struct Lisp_Fwd): New.
(Lisp_Intfwd, Lisp_Boolfwd, Lisp_Objfwd, Lisp_Buffer_Objfwd)
(Lisp_Kboard_Objfwd): The type is in in Lisp_Fwd.
(lispwfd): Is now a pointer to struct Lisp_Fwd.
(SYMBOL_BLV, SET_SYMBOL_FWD, XFWDTYPE, BUFFER_OBJFWDP): Update
accordingly.
(defvar_lisp, defvar_lisp_nopro, defvar_bool, defvar_int)
(defvar_kboard): These all take now a Lisp_Fwd.
(DEFVAR_LISP, DEFVAR_LISP_NOPRO, DEFVAR_BOOL, DEFVAR_INT)

(swap_in_symval_forwarding, find_symbol_value, set_internal)
(default_value, set_default_internal, make_blv, Fmake_local_variable):
Update accordingly.
The predicate field is always a builtin symbol. That means we know the
bit pattern at compile-time and they don't change at runtime.
* src/buffer.c (DEFVAR_PER_BUFFER): Create a const struct.
(defvar_per_buffer): Remove predicate and address arguments.
(syms_of_buffer): Instead of &BVAR (current_buffer, foo) use a plain foo
as argument to DEFVAR_PER_BUFFER.
* src/pdumper.c (dump_field_fwd): No more relocs needed for
Lisp_Fwd_Buffer_Obj and we can't apply them in the .rodata section.
The forwarding structs already exist in the data or bss section.
They are all created with DEFVAR_INT and similar macros. Instead
of creating new structs in the dump, create relocs to the data section.
* src/pdumper.c (dump_field_fwd): New.
(dump_blv, dump_symbol): Use it.
(dump_pre_dump_symbol): Don't dump fwd objects.
This restores the original behavior of 'overlays_in'. Changes in
this behavior had been made for cases of narrowing, but this
resulted in a regression with uses of 'remove-overlays'.

* test/src/buffer-tests.el (test-overlays-in-2)
(test-remove-overlays): Adjust expected results to accommodate

nsfns.m.

by truncating colspan.
* lisp/net/shr.el (shr-make-table-1): Ensure 'colspan' is a fixnum.
(Bug#80354)
* lisp/net/newst-backend.el (newsticker--parse-text-container):

through 'newsticker--unxml' to serialize back to a string.
(Bug#80317)
* lisp/language/indian.el (devanagari-composable-pattern): Account
for contextual positioning of punctuation signs when preceded by
a character. (Bug#80368)
Improve the Devanagari composition rules to account for contextual
positioning of punctuation signs when preceded by a character.
* lisp/help-fns.el (describe-mode--minor-modes): Add argument `buffer`.
(describe-mode): Use it to fix call to `documentation` so the
docstrings are computed in the right buffer and thus show
correctly when bindings are shadowed by minor modes.
Fix a typo in the documentation for the expected arguments when
calling smie-rules-function to set the indentation offset of
function arguments.
* doc/lispref/modes.texi (SMIE Indentation):
* lisp/emacs-lisp/smie.el (smie-rules-function): Fix typo in
documentation for smie-rules-function arguments.

faces rather than variables.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker):
Always evaporate 'prog1' when the tail is effect-free, even
when the value expression isn't.
* lisp/icomplete.el (icomplete-ret): No longer conditionalize on
icomplete-show-matches-on-no-input.
Suggested by Juri Linkov <juri@linkov.net> in bug#62108.
(icomplete-show-matches-on-no-input, icomplete-ret):
* etc/NEWS: Improve documentation.
* lisp/emacs-lisp/cond-star.el (cond*-non-exit-clause-p)
(cond*-non-exit-clause-substance): Don't consider a bind-and*
clause without ':non-exit' to be a non-exit clause (bug#80376).
(cond*):
* doc/lispref/control.texi (cond* Macro): Fix docs accordingly.
