to help-form for y-or-n-p.

directory-files-and-attributes.

* lisp/dired.el (directory-empty-p): Move function from here ...
* lisp/files.el (directory-empty-p): ... to here.
* lisp/net/ange-ftp.el (ange-ftp-directory-files): Call `nreverse' later.
* lisp/net/tramp.el (tramp-handle-directory-files):
* lisp/net/tramp-adb.el
(tramp-adb-handle-directory-files-and-attributes): Do not call
`nreverse'.
* src/dired.c (Fdirectory_files)
(Fdirectory_files_and_attributes): Fix docstrings.
* test/src/dired-tests.el: Removed. Tests moved to
test/lisp/dired-tests.el.
* test/lisp/dired-tests.el (dired-test-bug27899): Tag it :unstable.
(dired-test-directory-files)

to revert-buffer-insert-file-contents-function--default-function.
(revert-buffer-with-fine-grain-max-seconds): New variable. Passed as
argument MAX-SECS of replace-buffer-contents.

case-insensitive way before putting files in mhtml-mode. See

standard reference.

a test (bug#43511).
* lisp/files.el (directory-free-space-program): Doc fix; there is no
need to repeat that its obsolete here since it will be shown by
customize, describe-variable, etc. automatically.
This reverts commit de4f347901.
read-file-name already displays a long path when given a default
(like INITIAL in many other prompting functions), so using
format-prompt here is superfluous.
* lisp/files.el (save-some-buffers): Relax the "similarity" regexp
from the previous regexp: Don't show both file and buffer names if
the file is /tmp/foo and the buffer name is foo<zot>.
When loading a elc file search for a corresponding eln one into
`comp-eln-load-path' directories and load it if available.
`comp-eln-load-path' contains by default two directory (user and
system one).
* src/pdumper.c (dump_do_dump_relocation): While resurrecting from
load set eln cache sys dir in `Vcomp_eln_load_path'.
* src/lread.c (maybe_swap_for_eln): New function.

back to the master one.
(Fload): Make use of Vcomp_eln_to_el_h for the reverse file
look-up.

(openp_max_middledir_and_suffix_len, openp_fill_filename_buffer):
Remove functions.
(openp): As for Fload revert code modifications.
(openp): When a .elc file is being loaded check if a corresponding
eln can be loaded in place.
* src/comp.c (ELN_FILENAME_HASH_LEN): New macro.
(comp_hash_string): New function.
(hash_native_abi): Make use of 'comp_hash_string'.
(hash_native_abi): Change `comp-native-path-postfix' format.

(Vcomp_eln_to_el_h, Vcomp_eln_load_path): New global varaibles.
* lisp/startup.el (normal-top-level): Add user eln cache directory
in `comp-eln-load-path'.
* lisp/help-fns.el (find-lisp-object-file-name): Reverse look-up
files using `comp-eln-to-el-h'.

* lisp/emacs-lisp/find-func.el (find-library-name): Likewise.
* lisp/emacs-lisp/comp.el (comp-output-directory)
(comp-output-base-filename, comp-output-filename): Remove function.
(comp-compile-ctxt-to-file): Create parent directories if
necessary.
(comp-run-async-workers, native-compile, native-compile-async):
Make use `comp-el-to-eln-filename'.
This fixes the use case when, for example, 'find-file-hooks'
fails.
* lisp/files.el (find-alternate-file): If buffer 'oname' exists,
kill it before renaming the new one. (Bug#41359)
At least for me, 'auto-save-visited-mode' is very slow and blocks user
interaction for files visited over TRAMP. Therefore, I'd like a
mechanism to disable it for some buffers (namely, those visiting
remote files).
* (auto-save-visited-mode): Document that 'auto-save-visited-mode' can
be set to nil buffer-locally.
* etc/NEWS: Document new behavior.
Add a new function, file-modes-number-to-symbolic.
Make archive-int-to-mode and obsolete alias of it; use it
to define tar-grind-file-mode (Bug#27952).
* lisp/files.el (file-modes-number-to-symbolic): New defun.
* lisp/arc-mode.el (archive-int-to-mode): Make it an obsolete alias.
* lisp/tar-mode.el (tar-grind-file-mode):
Use file-modes-number-to-symbolic.
* test/lisp/arc-mode-tests.el (arc-mode-test-archive-int-to-mode)
* test/lisp/tar-mode-tests.el (tar-mode-test-tar-grind-file-mode):

(save-place-alist-to-file): Delimit file-local variables on the -*-
line with semicolons.
* lisp/files.el (auto-mode-alist): Use shy regexp group.
Fixes: bug#40573
The new mode can be used stand-alone or inherited from by modes
intended to edit programs. The existing emacs-lisp-mode and lisp-mode
are examples.
Thanks to Juri Linkov and Basil L. Contovounesios for researching some
data files in Emacs that can be automatically set to use the new mode.
* lisp/files.el (auto-mode-alist): Add entry for ".dir-locals" and
".dir-locals-2"
* lisp/emacs-lisp/lisp-mode.el: (lisp-data-mode): New major mode.
(lisp-mode): Inherit from lisp-data-mode. Set special lisp-mode
stuff here.
