new function (bug#51523).
* lisp/emacs-lisp/shortdoc.el (file): Mention it.
* lisp/net/mailcap.el (mailcap-parse-mailcaps): Read mailcaps again
only when at least one of the mailcap files has changed. Fixes
bug#51523.
* doc/lispref/files.texi (Reading from files): When the argument BEG or END to
insert-file-contents are at a byte position not at a character boundary,
clarify that raw bytes get inserted, and how to handle this awkwardness in
Lisp. Also clarify that insert-file-contents-literally is intended to insert
raw bytes into the buffer. Fix the outdated example that states it inserts
500 characters, when it actually inserts 500 bytes.
* doc/lispref/files.texi (Saving Buffers): Document it.

to heed `lock-file-name-transforms'.
(lock_file): Use it. Also remove likely buggy call to
dostounix_filename.
(unlock_file_body, Ffile_locked_p): Also use make_lock_file_name.
The primary idea is to allow `kill-buffer' and `kill-emacs' to
complete even if Emacs has trouble unlocking the buffer's file.

`display-error'.

This reverts most of commit 14fb657ba8
and its followup fixes, and instead fixes the original bugs in a
different manner that doesn't affect any unrelated use cases. As
part of this, the code which caused 'expand-file-name' to enforce
a trailing slash on expanded directories is removed, as this kind
of semantic processing is outside of 'expand-file-name's scope.
* src/fileio.c (Fexpand_file_name): If expanding default_directory
yields a remote file name, call its handlers. (Bug#26911)
(Bug#34834)
* doc/lispref/files.texi (File Name Expansion): Remove the
requirement that expanding a directory name yields a directory
name, i.e. that the expansion must end in a slash.
* etc/NEWS: Remove the announcement of the changed behavior of
'expand-file-name' wrt trailing slashes.
* test/src/fileio-tests.el (fileio-tests--HOME-trailing-slash)
(fileio-tests--expand-file-name-trailing-slash): Remove tests.
* test/lisp/net/tramp-tests.el (tramp-test05-expand-file-name): No
need to expect different results in Emacs 28 and later.
Problem reported by Yegor Timoshenko (Bug#26911),
and I ran into it myself recently in normal-top-level.
* doc/lispref/files.texi (File Name Expansion), etc/NEWS: Mention this.
* src/fileio.c (Fexpand_file_name): Expand "/a/b/." to "/a/b/" not
"/a/b", to avoid misinterpreting a symlink "/a/b". Similarly,
expand "/a/b/c/.." to "/a/b/" not "/a/b".
* test/lisp/net/tramp-tests.el (tramp-test05-expand-file-name):
Adjust to match new behavior.
(tramp-test05-expand-file-name-relative): This test now succeeds,
at least on Fedora 31.

(fileio-tests--expand-file-name-trailing-slash) New test.

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.

* doc/lispref/files.texi (Changing Files): Document the new funtion.
* etc/NEWS (Lisp Changes in Emacs 28.1): Announce it.
This is a companion to the recent set-file-modes patch.
It adds support for a ‘nofollow’ flag to set-file-times (Bug#39773).
Like the set-file-modes patch, it needs work in the w32 port.
* admin/merge-gnulib (GNULIB_MODULES): Add futimens, utimensat.
Remove utimens.
* doc/lispref/files.texi (Changing Files):
* etc/NEWS: Mention the change.

When setting file times, avoid following symbolic links
when the file is not supposed to be a symbolic link.
* lib/futimens.c, lib/utimensat.c, m4/futimens.m4, m4/utimensat.m4:
New files, copied from Gnulib.
* lisp/gnus/gnus-cloud.el (gnus-cloud-replace-file):

and add a FIXME comment for it.
* lisp/net/tramp-gvfs.el (tramp-gvfs-handle-set-file-times):
* src/fileio.c (Fset_file_times):
Support an optional FLAG arg.
* src/fileio.c (Fcopy_file): Use futimens instead of set_file_times,
as it’s simpler and is a POSIX API.
* src/sysdep.c (set_file_times): Move from here ...
* src/w32.c (set_file_times): ... to here, and make it static,
since it is now used only in w32.c. Presumably w32.c should also
add support for futimens and utimensat (the POSIX APIs, which
Emacs now uses) and it can remove fdutimens (the Gnulib API,
which Emacs no longer uses).
This avoids some race conditions (Bug#39683). E.g., if some other
program changes a file to a symlink between the time Emacs creates
the file and the time it changes the file’s permissions, using the
new flag prevents Emacs from inadvertently changing the
permissions of a victim in some completely unrelated directory.
* admin/merge-gnulib (GNULIB_MODULES): Add fchmodat.
