* lisp/pixel-scroll.el (pixel-scroll-precision-scroll-down): Get
rid of big motion loop.
(pixel-scroll-precision-scroll-up): Stop subtracting height of
window lines.
* src/comp.c (maybe_defer_native_compilation): Update to accumulate
delayed objects in `comp--delayed-sources'.
(syms_of_comp): Add `comp--delayed-sources' and `comp--loadable'
vars.
* lisp/startup.el (startup--honor-delayed-native-compilations): New
function.
(normal-top-level): Call it.
* doc/emacs/regs.texi (File and Buffer Registers): Rename and add
doc for `buffer' version.
* lisp/register.el (register-val-jump-to, register-val-describe):
Add support for (buffer . ...) registers (bug#33033).
* lisp/emacs-lisp/generator.el (cps--transform-1):
Eliminate a temporary for the last of any `let` form, not just for
single-binding ones. Suggested by Stefan Monnier.
This fixes most of the problem, but with a large image the
vscroll can sometimes jump about, which has to be fixed.
* lisp/pixel-scroll.el (pixel-scroll-precision-up): Handle
vscrolling large images in the first unseen line.
* lisp/emacs-lisp/generator.el (cps--transform-1):
Don't translate single-binding `let` into `let*` with an extra
temporary variable; it just adds two more useless states.
* lisp/net/shr.el (shr-char-breakable-p, shr-char-nospace-p)
(shr-char-kinsoku-bol-p, shr-char-kinsoku-eol-p)
(shr-find-fill-point): Moved to pixel-fill.el and renamed.
(shr-pixel-region): Made obsolete.
(shr-fill-line): Use pixel-fill-region.
* lisp/textmodes/pixel-fill.el: New package.
* lisp/keymap.el (keymap-set): Fix handling of binding one key to
another key.
(keymap-substitute): Fix confusion in implementation -- the args
are definitions, not keys.
* lisp/progmodes/project.el
(project-kill-buffers-display-buffer-list): Option to toggle
temporarily display of the list of buffers to kill when calling
project-kill-buffers
(project-kill-buffers): Handle
project-kill-buffers-display-buffer-list option (bug#52148).
* etc/NEWS: Mention the new variable.
* lisp/apropos.el (apropos-describe-plist): Bind the new
variable (bug#52053).
* lisp/button.el (button-describe): Bind the new variable.
* lisp/help-fns.el (describe-function, describe-variable)
(describe-face, describe-symbol, describe-syntax)
(describe-categories, describe-keymap, describe-mode)
(describe-widget): Bind the new variable.
* lisp/help-macro.el (make-help-screen): Bind the new variable.
* lisp/help.el (help-buffer-under-preparation): New variable
that is bound to t by commands that create a *Help* buffer.
(substitute-command-keys): Use the new variable:
help-link-key-to-documentation is supposed to have an effect
only "in *Help* buffers". Fixes bug#52053.
(view-lossage, describe-bindings, describe-key): Bind the new
variable.
* lisp/repeat.el (describe-repeat-maps): Bind the new variable.
* lisp/international/mule-cmds.el (describe-input-method)
(describe-language-environment): Bind the new variable.
* lisp/international/mule-diag.el (describe-character-set)
(describe-coding-system, describe-font, describe-fontset)
((list-fontsets): Bind the new variable.
* lisp/emacs-lisp/byte-run.el (byte-run--set-compiler-macro):
Don't warn when a compiler macro with lambda-form expander does not
use all the arguments of the function. Nobody expected any warning
since the arguments look like free variables inside the lambda form.
* lisp/mh-e/mh-comp.el (mh-forwarded-letter-subject): Collapse
two-line From headers into a single line (SF#266). Based on a
suggestion from Lester Buck (many thanks!).
* lisp/pixel-scroll.el (pixel-point-at-unseen-line): Rewrite
to use `pixel-point-and-height-at-unseen-line'.
(pixel-point-and-height-at-unseen-line): New function.
(pixel-scroll-precision-scroll-up): Use existing logic
to determine unseen line position.
