* lisp/play/gamegrid.el (gamegrid-add-score-with-update-game-score-1):
Don't signal an error with a score that is too low to add to the list
of top scores.
Fixes: debbugs:12779
* configure.ac (fpathconf): Remove unnecessary check.
* admin/CPP-DEFINES (HAVE_FPATHCONF): Remove.
* src/process.c (pty_max_bytes): Remove; unused.
(send_process): Do not set it.
* window.el (enlarge-window, shrink-window): Don't mention return
value in doc-string (Bug#12896).
(window--display-buffer): Don't resize frames - it won't work
with all window managers and defeat pop-up-frame-alist.
(display-buffer-alist): In doc-string explain that CONDITION can
be a function and which arguments are passed to it (Bug#12854).
(display-buffer-assq-regexp): New argument ACTION. Handle lambda
expressions (Bug#12854).
(display-buffer): Pass ACTION argument to
display-buffer-assq-regexp.
* windows.texi (Choosing Window): Rewrite description of
display-buffer-alist (Bug#12167).
(Display Action Functions): Mention inhibit-switch-frame. Fix
description of display-buffer-below-selected. Reorder actions.
Add example (Bug#12848).
* doc/misc/cl.texi (Function Bindings): Clarify that cl-flet is lexical.
(Obsolete Macros): Move example here from Function Bindings.
* etc/NEWS: Related edit.
* lisp/faces.el (face-underline-p): Doc fix. Handle :underline being
things other than `t' (a string, a list).
(face-inverse-video-p): Doc fix.
(set-face-underline): Rename it back from set-face-underline-p.
Doc fix. Allow interactive input of values other than t.
(read-face-attribute): Apply formatting to :underline,
since like :box and :stipple it can take list values.
* doc/lispref/display.texi (Face Attributes): Fix :underline COLOR description.
(Attribute Functions): Update for set-face-underline rename.
Tweak descriptions of face-underline-p, face-inverse-video-p.
* etc/NEWS: Related edit.
of vectorlike_header, garbage-collect and gc-cons-threshold.
(Object Internals): Explain Lisp_Object layout and the basics
of an internal type system.
(Buffer Internals): Update description of struct buffer.
(advice--buffer-local-function-sample): New var.
(advice--set-buffer-local, advice--buffer-local): New functions.
(add-function, remove-function): Use them.
* semantic/symref/list.el (semantic-symref-symbol): Use
`semantic-complete-read-tag-project' instead of
`semantic-complete-read-tag-buffer-deep', since the latter is not
working correctly.
* semantic/symref.el (semantic-symref-result-get-tags): Use
`find-buffer-visiting' to follow symbolic links.
* semantic/fw.el (semantic-find-file-noselect): Always set
`enable-local-variables' to `:safe' when loading files.
nt/inc/unistd.h (faccessat): Add prototype.
(AT_FDCWD, AT_EACCESS, AT_SYMLINK_NOFOLLOW): New macros; the first
2 moved from ms-w32.h.
nt/inc/ms-w32.h (AT_FDCWD, AT_EACCESS, faccessat): Remove macros.
src/w32.c (faccessat): Rename from sys_faccessat. (No need to use a
different name, as the MS runtime does not have such a function,
and probably never will.) All callers changed. Ignore DIRFD
value if PATH is an absolute file name, to match Posix spec
better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
symlinks.
Fixes: debbugs:12632
src/w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
use the same value of thread handle.
(start_timer_thread): If the timer thread exited (due to error),
clean up by closing the two handles it used. Duplicate the caller
thread's handle here, so it gets duplicated only once, when
launching the timer thread. Set priority of the timer thread, not
the caller thread.
(getitimer): Don't duplicate the caller thread's handle here.
(ruby-syntax-propertize-function): After everything else, search
for expansions in string literals, mark their insides as
whitespace syntax and save match data for font-lock.
(ruby-font-lock-keywords): Highlight just the 2nd group from
expression expansion matches.
(ruby-match-expression-expansion): Use the match data saved to the
text property in ruby-syntax-propertize-function.
* test/automated/ruby-mode-tests.el
Change direct font-lock face references to var references.
(ruby-interpolation-suppresses-syntax-inside): New test.
(ruby-interpolation-inside-percent-literal-with-paren): New
failing test.
