* lisp/simple.el (get-scratch-buffer-create): Revert last changes.
* src/window.c (Fset_window_configuration): Force recalculation of
Vwindow_list after restoring the windows.
* src/buffer.c (other_buffer_safely): Make sure we always return a
valid buffer, even if 'get-scratch-buffer-create' signals an
error.
* lisp/startup.el (initial-scratch-message): Don't use \\[...]
commands for substitute-command-keys.
* lisp/simple.el (get-scratch-buffer-create): Don't call
substitute-command-keys on initial-scratch-message, to avoid
signaling an error in rare cases. (Bug#60096)
* lisp/startup.el (command-line): Interpret non-absolute file
names in '--init-directory' relative to the directory from
which Emacs is started. (Bug#59795)
* doc/lispref/compile.texi (Native-Compilation Variables):
Document it.

inhibit-native-compilation.
(maybe_defer_native_compilation): Use it.
* lisp/startup.el (normal-top-level): Move setting of
'window-point-insertion-type' from here...
* lisp/simple.el (messages-buffer-mode): ...to here. This is so
any *Messages* buffers we create instead of the original one, if
it's killed, will have the same type of the window-point marker.
(Bug#57466)
* lisp/startup.el (command-line-1, normal-top-level): Reset the
default face's font only if 'face-font-rescale-alist' affects that
face's font. For the use case where it matters, see
https://lists.gnu.org/archive/html/emacs-devel/2022-07/msg00157.html.
Make the 'inhibit-startup-screen' and non-inhibit branches behave
the same in that case.
* lisp/startup.el (startup-redirect-eln-cache, normal-top-level):
Don't create the nativecomp directory here, because this led to
brittle deletions of the directory -- there would be several
instances of the directory left over after a test run.
* lisp/emacs-lisp/ert.el (ert-run-tests-batch-and-exit): Create
the nativecomp directory.
* lisp/simple.el (get-scratch-buffer-create): New function, factored
out of scratch-buffer, and additionally clearing the modification flag
and calling substitute-command-keys (bug#55257).

* lisp/startup.el (command-line): Remove references to a wrong bug
number and improve comments for delaying the 'user-emacs-directory'
warning. (Bug#25163)
* lisp/startup.el (command-line): If user-emacs-directory is not
accessible, delay to show a warning until all command line args
are processed (bug#25163).
There are custom entries that contain lambda's as values by default,
which can result in them containing embedded NULs after
byte-compilation, which wreaks havoc when they are saved to .emacs and
later read in. (Bug#52554)
* lisp/cus-edit.el (custom-save-all): Bind
print-escape-control-characters to t.
* lisp/startup.el (startup--load-user-init-file): Bind
inhibit-null-byte-detection to t.

avoids erroring out if it turns out there's no forms in the buffer
(bug#4616).

* lisp/international/mule.el (load-with-code-conversion): Accept
an eval function.
* lisp/startup.el (startup-redirect-eln-cache)
(startup--update-eln-cache): New functions.
(startup--original-eln-load-path): New defvar.
(normal-top-level): Record the original value of
'native-comp-eln-load-path' in 'startup--original-eln-load-path'.
Do not amend 'native-comp-eln-load-path' here, as that could
overwrite user customizations.
(command-line): Amend 'native-comp-eln-load-path' after loading
the early-init file, and then again after loading the user init
file. (Bug#53891)
* etc/NEWS: Announce 'startup-redirect-eln-cache'.
* lisp/startup.el (normal-top-level): Set up the initial value of
'native-comp-eln-load-path' early into startup, then amend it
after calling 'command-line'. (Bug#53497)

* lisp/startup.el (normal-top-level): Move the eln init to after
we've processed the command line arguments.
(command-line): Interpret the --init-directory switch.
* src/emacs.c (standard_args): Add.
* lisp/startup.el (startup--require-comp-safetly): New function.

`startup--require-comp-safetly'.

documentation of 'lisp-directory' and related features.
Since the location of those files changes between build time and
installation time, this requires to tweak the file name used in those
(#$ . NNN) references during the dump so they don't hardcode the build
directory. We do it in the same way as was already done for those
same file names in `load-history`, except we convert them back to
absolute file names more lazily (i.e. when fetching the actual
docstring rather than at startup), which requires remembering the
`lisp-dir` computed at startup in the new `lisp-directory` variable.
* src/Makefile.in ($(etc)/DOC): Don't scan Lisp files any more.
* src/lread.c (Fload): Use relative file names for `load-file-name`
when preloading for the dump, like we already did for `current-load-list`.
(read_list): Don't zero-out dynamic docstring references during the
preload since they won't be filled later by Snarf-documentation any more.
(read1): Remove the hash-hack for doc references that were zeroed.
* lisp/startup.el (lisp-directory): New variable.
(command-line): Set it.
* src/doc.c (get_doc_string): Use `lisp-directory` for dynamic
docstring references using relative file names.
(syms_of_doc): Add `Qlisp_directory`.
* lib-src/make-docfile.c (scan_file): Don't handle `.el` or `.elc`
files any more.
(IS_SLASH): Remove macro, not used any more.
(skip_white, read_lisp_symbol, search_lisp_doc_at_eol)
(scan_lisp_file): Remove functions, not used any more.
* doc/lispref/loading.texi (Library Search): Mention `lisp-directory`.
* lisp/startup.el (fancy-startup-text, fancy-about-text)
(fancy-splash-head, normal-about-screen): Let-bind browse-url-browser-function
to eww-browse-url around functions that use browse-url.
(fancy-startup-screen, fancy-about-screen): Don't set buffer-local
browse-url-browser-function.
