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.
* lisp/startup.el (command-line--load-script): New function that
avoids erroring out if it turns out there's no forms in the buffer
(bug#4616).
* lisp/subr.el (delete-line): New utility function.
* 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)
* doc/emacs/cmdargs.texi (Initial Options): Mention it.
* 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--honor-delayed-native-compilations): Make use of
`startup--require-comp-safetly'.
* src/comp.c (CALL0I): New define.
(maybe_defer_native_compilation): Make use of
`startup--require-comp-safetly'.
* lisp/startup.el (lisp-directory):
* etc/NEWS:
* doc/lispref/loading.texi (Library Search): Improve wording of
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.

* 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.
* lisp/startup.el (fancy-startup-tail):
(normal-mouse-startup-screen):
(normal-no-mouse-startup-screen): Fill the Emacs version data,
since it's usually longer than a single line, anyway.
* lisp/startup.el (command-line-1): Fix breakage with
(file-truename "/dev/stdin") => "/proc/227795/fd/pipe:[1381505]"
when using /dev/stdin as a --script parameter.
* lisp/startup.el (normal-top-level): Make startup more robust --
we may not be allowed to create any directories when running under
test mode (bug#48350).
* lisp/dnd.el (dnd-open-local-file): Add file to history.
* lisp/files.el (file-name-history--add): New function (bug#12915).
* lisp/startup.el (command-line-1): Add file to history.
* lisp/startup.el (command-line-1): When loading a file, use the
truename so that eval-after-load works more reliably (bug#49009).
