* lisp/emacs-lisp/let-alist.el (let-alist): Improve docs.
Namely, clarify that 'let-alist' does not "see" symbols
introduced by macro-expansion in its body, and that the
generated code looks up symbols in the alist whether or not
they are actually used in runtime.
See also bug#79706 for some relevant discussion.
* doc/lispref/lists.texi (Building Lists): Document it.
* etc/NEWS: Mention it.
* lisp/emacs-lisp/shortdoc.el (list): Demonstrate it.
* lisp/subr.el (ensure-proper-list): Add it.
* doc/emacs/custom.texi (Newcomers Theme): Move to the beginning
of the node, so as to be visible even when the Emacs frame is
too small and wrap it in a conditional to not print the message
in non-Info outputs.
* doc/misc/use-package.texi (Install package): Add an example
block that doesn't use :rev, and instead shows that you can just
pass a URL as a string to :vc.

it.
* etc/NEWS (bindings): Mention it.
* etc/themes/newcomers-presets-theme.el (newcomers-presets): Add
it.

(global-xref-mouse-mode): Implement it.
Remove `error-data` from the new error API: it is not really
compatible with a more abstract view of error descriptors, and
in practice it seems to be used only in two ways (both of them rare):
- To add some contextual info to an error. We should maybe add
a dedicated support for that, but it's not clear what shape it
should take, ideally (there was a discussion about with Alan
and myself in emacs-devel a few years ago).
- To do some other massaging whose correctness is dubious anyway.
* doc/lispref/control.texi (Handling Errors): Remove `error-data`.
* lisp/epa-file.el (epa-file--find-file-not-found-function): Don't use
`error-data`.

`epa-file-insert-file-contents`.
(epa-file-insert-file-contents): Use it instead of `error-data`.
* lisp/subr.el (error-data): Delete function.
Define new functions to manipulate error descriptors and
add support for `signal` to *re*signal a previous error.
* src/eval.c (Fsignal): Make the second arg optional and document
the possibility of passing a whole error descriptor to re-signal it.
(signal_or_quit): Fix a few corner case issues when
DATA is `nil` and ERROR_SYMBOL is an error descriptor.
* lisp/subr.el (error-type-p, error--p, error-type, error-data)
(error-has-type-p, error-slot-value): New function.
* doc/lispref/control.texi (Handling Errors): Prefer "error descriptor"
to "error description". Use the new single-arg call to `signal` to
re-throw an error.
Document `error-type`, `error-data` and `error-slot-value`.

`error-has-type-p`.

* lisp/vc/vc.el (vc-checkin): Adjust message to end in
"...failed" not "...done" when async command exits non-zero.
* doc/misc/viper.texi: Fix weird use of indexing, whereby many
index entries were placed _after_ the table which described the
functions or variables or keys, or even in the end of a @node
describing some subject. The index entries were moved to _before_
the text to which they pertain. Also, fix some incorrect
cross-references.
Walking the window tree is more reliable than using the selected
window. Implement 'get-mru-frame' on top of 'get-mru-frames'
using 'frame-use-time'.

for the specified frame.

Not a bug report, but this is from the emacs-devel thread
"Tree-sitter: Transcendental things".
Improve tree-sitter thing navigation functions to handle the
case where there are multiple nested parsers in the
buffer. Previously these functions just grab the node at point
and are limited to the parser of that node. Now these functions
will thoUrouly search through all parsers that covers point
before giving up.
* doc/lispref/parsing.texi: Mention the change.
* lisp/treesit.el (treesit--some): New macro.
(treesit--thing-sibling): Use the new macro, add a new PARSER
parameter.

parameter. Also pass the PARSER arg to recursive calls and
calls to treesit-thing-prev, etc.

Set it only if we're outputting TeX.
(Lists diagrammed, Lists diagrammed, Lists diagrammed)
(Lists diagrammed, Lists diagrammed, Symbols as Chest)
(kill-ring-yank-pointer, lambda): Presume that
`print-postscript-figures` is set only for TeX output and remove
the `@tex...@end tex` around `@image` which do not seem relevant any more.
* src/lisp.h (FOR_EACH_TAIL_INTERNAL): Divvy up the code into...
(FOR_EACH_TAIL_BASIC, FOR_EACH_TAIL_STEP_CYCLEP): ...these macros,

but now detecting cycles in the other argument.

new month at the edge instead of the second month segment, to
prevent the cursor from jumping back and forth. This is
consistent with the behavior of calendar-forward-day/week.

cursor with respect to the window, when the old date is out of
view.

(holiday-chinese): Replace displayed-year/month with the actual
calendar range, and look up holidays in all visible years.
