* 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.

(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.

(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)

(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'.

We don't need a special initializer for the minor mode, if we
are not enabling the option OOTB.

produce HTML with such. Make it possible for SHR to render such HTML
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):
Only "xhtml" type contains inline XML nodes that need to be run
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.

(makefile-makepp-font-lock-keywords): Use `font-lock-*-face`
faces rather than variables.

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.
