* lisp/gnus/nnoo.el (noo-import-1, nnoo-define-skeleton-1): Use `dolist`.
(noo-map-functions, nnoo-define-basics): Directly emit the code rather than
going through an intermediate function; this also avoids the use of `eval`.

folded into their corresponding macro.

`symbol-value`.
* lisp/gnus/gnus-art.el (gnus-button-handle-describe-key): Avoid `eval`
since `kbd` is a function nowadays.

* lisp/gnus/gnus-group.el (gnus-cache-active-hashtb): Use `defvar`.

avoids the risk of name capture anyway.
(gnus-group-delete-articles): Actually use the `oldp` arg.
* lisp/gnus/gnus-html.el (gnus-html-wash-images): Fix debug message so
it's emitted after the `url` var it prints is actually initialized.
And avoid `setq` while we're at it.
* lisp/gnus/gnus-msg.el (gnus-group-mail, gnus-group-news)
(gnus-summary-mail-other-window, gnus-summary-news-other-window):
Merge `let`s using `let*`.

Tighten the scope of `buffer`, and tighten a regexp.
(gnus-parse-simple-format): Reduce code duplication.
* lisp/gnus/gnus-start.el (gnus-child-mode): Don't `defvar` it since we
never use that variable and accordingly don't define it as a minor mode.
* lisp/gnus/gnus-util.el (gnus-byte-compile): Simplify so it obeys
`gnus-use-byte-compile` not just on the first call.
(iswitchb-minibuffer-setup): Declare.

* lisp/gnus/nnweb.el (nnweb-request-article): Avoid `setq`.
* lisp/gnus/spam.el (BBDB): Use the `noerror` arg of `require`, and
define all the functions for BBDB regardless if the require succeeded.
(spam-exists-in-BBDB-p): Don't inline, not worth it.
* lisp/gnus/gnus-sum.el (gnus-summary-thread-level)
(gnus-summary-article-mark): Turn macros into `defsubst`.
* lisp/gnus/mail-source.el (mail-source-bind-common): Actually use its arg.
* lisp/gnus/nntp.el (nntp-copy-to-buffer): Turn macro into a `defsubst`.
(nntp-wait-for, nntp-retrieve-data, nntp-send-command): Don't inline
those, it's not worth it.
* lisp/gnus/nnoo.el (defvoo, deffoo, nnoo-declare, nnoo-import)
(nnoo-map-functions):
* lisp/gnus/nnmaildir.el (nnmaildir--with-nntp-buffer)
(nnmaildir--with-work-buffer, nnmaildir--with-nov-buffer)
(nnmaildir--with-move-buffer, nnmaildir--condcase):
* lisp/gnus/mm-decode.el (mm-with-part):
* lisp/gnus/gnus-msg.el (gnus-setup-message):
* lisp/gnus/gnus-agent.el (gnus-agent-with-fetch, gnus-agent-while-plugged):
* lisp/gnus/mail-source.el (mail-source-set-1, mail-source-value):
Use `declare`.
* lisp/gnus/gnus-util.el (gnus-define-keys): Use `declare`, and also
don't quote `keymap` if it's a variable name.
(gnus-define-keys-1): Reject the case where `keymap` is a variable name.
(gnus-eval-in-buffer-window, gnus-define-keys-safe)
(gnus-define-keymap, gnus-atomic-progn, gnus-with-output-to-file)
(gnus-parse-without-error): Use `declare`.
(gnus-atomic-progn-assign, gnus-atomic-setq): Delete macros.
* lisp/gnus/gnus-undo.el (gnus-undo-register): Drop indent and edebug spec
since they're not really appropriate for a function.
* lisp/gnus/gnus-art.el (gnus--\,@): New macro.
Use it at top-level to construct the `gnus-article-FOO` => `article-FOO`
wrapper functions.
(gnus-with-article-headers, gnus-with-article-buffer): Use `declare`.
* lisp/mail/rmail.el (rmail-show-message-set-modified): New
option.
(rmail-show-message-1): If 'rmail-show-message-set-modified' is
non-nil, don't reset the buffer's modified state. (Bug#45941)
* etc/NEWS: Announce the new option.
* lisp/dired.el (dired-clean-up-after-deletion): Kill the buffers
if you have `dired-clean-up-buffers-too' set and
`dired-clean-confirm-killing-deleted-buffers' nil (bug#38037).
Copyright-paperwork-exempt: yes
* lisp/vc/vc-dir.el (vc-dir-mode-map):
Remove the mouse-2 binding (bug#13692).

(vc-default-dir-printer): Use it on the state buttons.
* lisp/vc/vc-git.el (vc-git-dir-printer): Same.
* lisp/play/handwrite.el: Use lexical-binding. Remove redundant
:group args. Minor cleanups.

(handwrite-set-pagenumber-off, handwrite-set-pagenumber-on): Make
comments into docstrings.
* simple.el (shell-command, shell-command-on-region): Set
revert-buffer-function buffer-locally, not globally. Also, avoid an
unnecessary call to (current-buffer) by taking advantage of the
closure (bug#46151).
* lisp/generic-x.el (generic-mode-ini-file-find-file-hook): Fix my
previous commit; for some reason 'function' produces a warning here
while 'quote' does not.
* lisp/emacs-lisp/bindat.el: Use lexical-binding.
(bindat--unpack-group, bindat--length-group, bindat--pack-group):
Declare `last` and `tag` as dyn-scoped.
(bindat-unpack, bindat-pack): Bind `bindat-raw` and `bindat-idx` via
`let` rather than via the formal arglist.
* lisp/emacs-lisp/package-x.el:

Remove correspondingly redundant declarations.

Fix name of `curcell-overlay` variable.
* lisp/emacs-lisp/unsafep.el: Use lexical-binding.
(unsafep): Bind `unsafep-vars` via `let` rather than via the formal arglist.
