* 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.

(ediff-clone-buffer-for-current-diff-comparison): Compute the buf-type
rather than taking it as as argument.
(ediff-inferior-compare-regions): Adjust calls accordingly.
Fixes: debbugs:11319
(json-encoding-separator, json-encoding-default-indentation)
(json--encoding-current-indentation, json-encoding-pretty-print)
(json-encoding-lisp-style-closings): New vars.
(json--with-indentation): New macro.
(json-encode-hash-table, json-encode-alist, json-encode-plist)
(json-encode-array): Use it to obey json-encoding-pretty-print.
(json-pretty-print-buffer, json-pretty-print): New commands.
Fixes: debbugs:12634
src/w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
try to get accurate owner and group information from NT file
security APIs. This is to make most callers of 'stat' and
'lstat', which don't need that information, much faster.
src/dired.c (Ffile_attributes) [WINDOWSNT]: Set
w32_stat_get_owner_group to a non-zero value, to request accurate
owner and group information from 'lstat'.
nt/inc/sys/stat.h: Declare w32_stat_get_owner_group.
Extract `ruby-syntax-propertize-expansions'.
(ruby-syntax-propertize-expansions): Only change syntax on
certain string delimiters, to punctuation. This way the common
functions like forward-word and thing-at-point still work.
(ruby-match-expression-expansion): Improve readability.
(ruby-block-contains-point): New function.
(ruby-add-log-current-method): Handle several edge cases.
* test/automated/ruby-mode-tests.el
Rename one interpolation test; add three more.
(ruby-with-temp-buffer): New macro, use it where appropriate.
(ruby-add-log-current-method-examples): Use "_" for target point.
Add four tests for ruby-add-log-current-method.
Extract `ruby-syntax-propertize-expansions'.
(ruby-syntax-propertize-expansions): Only change syntax on
certain string delimiters, to punctuation. This way the common
functions like forward-word and thing-at-point still work.
* test/automated/ruby-mode-tests.el
Rename one interpolation test; add three more.
as that confuses set-auto-coding, so insist on the head-read
returning the full 1024 bytes. Let lseek compute the tail offset;
less work for us. Do not ignore I/O errors when reading the tail.
(edebug-unload-function): Make sure that unload-feature finishes even when
aborting an ongoing edebug session. Also, do not worry about edebug-mode,
unload-feature takes care of it.
* xdisp.c (markpos_of_region): New function.
(init_iterator): Do not highlight the region of zero length.
(redisplay_window): Check whether the region is of non-zero length.
(try_cursor_movement): Allow if the region length is zero.
(try_window_reusing_current_matrix, try_window_id): Likewise.
fstat shouldn't fail, and if it does fail copy-file should not proceed.
Remove unnecessary S_ISLNK test, as (contra the comments) this
function can't copy symlinks. Improve quality of error message
when attempting to copy files that are neither regular files nor
directories.
(toggle-frame-maximized): Toggle frame maximization according to
`frame-maximization-style', bound to <f11>.
(cycle-frame-maximized): Cycle between all maximization styles and
non-maximized frame, bound to shift-<f11>.
