* configure.ac (acl): New option.
(HAVE_POSIX_ACL): Test for POSIX ACL support. This is typically
provided by libacl on GNU/Linux.
* fileio.c (Ffile_acl, Fset_file_acl): New functions.
(Fcopy_file): Change last arg to `preserve_extended_attributes'
and copy ACL entries of file in addition to SELinux context if
set.
(syms_of_fileio): Add `file-acl' and `set-file-acl'.
* Makefile.in (LIBACL_LIBS): New macro.
(LIBES): Use it.
* files.el (file-extended-attributes)
(set-file-extended-attributes): New functions.
(backup-buffer): Use them to handle both SELinux context and ACL
entries.
(backup-buffer-copy): Work with an alist of extended attributes,
rather than an SELinux context.
(basic-save-buffer-2): Ditto.
* files.texi (File Attributes): Document ACL support and new
`file-acl' function.
(Changing Files): Mention argument name change of `copy-file' and
document new function `set-file-acl'.
* configure.ac (BSD4_2): Remove; no longer needed.
* admin/CPP-DEFINES (BSD4_2): Remove.
* doc/lispintro/emacs-lisp-intro.texi (Files List):
directory-files-and-attributes now outputs t for attribute that's
now a placeholder.
* doc/lispref/files.texi (Testing Accessibility): Document GROUP arg
of file-ownership-preserved-p.
(File Attributes): Document that 9th element is now
just a placeholder.
* doc/lispref/os.texi (User Identification): Document new functions group-gid,
group-real-gid.
* etc/NEWS: Document changes to file-attributes,
file-ownership-preserved-p.
Mention new functions group-gid, group-real-gid.
* lisp/files.el (backup-buffer): Don't rely on 9th output of
file-attributes, as it's now a placeholder. Instead, use the new
optional arg of file-ownership-preserved-p.
(file-ownership-preserved-p): New optional arg GROUP.
Fix mishandling of setuid directories that would cause this
function to return t when it should have returned nil.
Document what happens if the file does not exist, and when
it's not known whether the ownership will be preserved.
* lisp/net/tramp-sh.el (tramp-sh-handle-file-ownership-preserved-p):
Likewise.
(tramp-get-local-gid): Use group-gid for integer, as that's
faster and more reliable.
* src/dired.c (Ffile_attributes): Return t as the 9th attribute,
to mark it as a placeholder. The old value was often wrong.
The only user of this attribute has been changed to use
file-ownership-preserved-p instead, with its new group arg.
* src/editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
Fixes: debbugs:13125
Be more systematic about using "@." (not ".") at end of sentence that
ends in a capital letter, and about appending "@:" after non-ends of
sentences that end in a lower case letter followed by "." followed by
whitespace. Omit unnecessary use of "@:" and "@.". Similarly for "?"
and "!". Be more consistent about putting a comma after "i.e." and
"e.g."; this is the typical American style and it's easier to code in
Texinfo.

These instances were missed the first time around.

FORCE-SAME-WINDOW arg to switch-to-buffer and
switch-to-buffer-other-frame. Delete duplicate
replace-buffer-in-windows doc.
(Choosing Window): Document display actions.
