+
+ Fix display of R2L lines when the last character fits only partially.
+ See http://lists.gnu.org/archive/html/emacs-devel/2014-07/msg00476.html
+ for the details.
+ * xdisp.c (extend_face_to_end_of_line): If the last glyph of an
+ R2L row is visible only partially, give the row a negative x
+ offset.
+ (display_line): Fix the calculation of the glyph whose pixel width
+ is used to decide whether the last produced glyph fits on the
+ line. When the last glyph fits only partially, give the row a
+ negative x offset.
+
+ Fix hscroll of R2L lines that begin with a TAB or another wide glyph.
+ * xdisp.c (append_stretch_glyph): In a R2L glyph row, decrease the
+ pixel width of the first glyph that is hscrolled from display.
+ (display_line): In R2L glyph rows, don't give a negative offset to
+ row->x when the first glyph begins before first_visible_x.
+
+ * xdisp.c (display_line): If called with iterator set up to write
+ to a marginal area, delay the call to handle_line_prefix until we
+ switch back to the text area. (Bug#18035)
+
+ * .gdbinit (xwindow): The members total_cols, total_lines,
+ left_col, and top_line are C integers (and has been so for the
+ last 1.5 years).

+
+ * macros.c (Fstart_kbd_macro): Initialize kbd_macro_ptr and
+ kbd_macro_end together with kbd_macro_buffer. (Bug#18140)
+
+2014-08-01 Dmitry Antipov <dmantipov@yandex.ru>

+ * atimer.c (toplevel) [HAVE_TIMERFD]: Include errno.h.
+ (timerfd_callback): Ignore weird events with no data. Add tight
+ assertions and comments.
+ (init_atimer) [HAVE_TIMERFD]: Add environment variable to optionally
+ disable timerfd-based timer. Use TFD_NONBLOCK for timer descriptor.
+
+2014-08-01 Paul Eggert <eggert@cs.ucla.edu>

+ * frame.c (x_set_frame_parameters): Fix typo in previous patch.
+ I had confused && with ||.
+
+2014-07-31 Paul Eggert <eggert@cs.ucla.edu>

+ (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
+ Fall back on timer_create if timerfd_create fails at runtime.

+ (turn_on_atimers): Clear timer_create-based timers too,
+ for consistency.
+
+ * frame.c (x_set_frame_parameters): Don't use uninitialized locals.

+ in either case this leads to undefined behavior.
+

+ FRAME_X_WINDOW when calling x_set_window_size (Bug#18138).
+
+2014-07-28 Martin Rudalics <rudalics@gmx.at>
+
+ * frame.c (x_set_frame_parameters): Revert part of 2014-07-24
+ change that added the top margin height to the requested height
+ and revert (undocumented) part of 2014-07-28 change that changed
+ the logic of whether a size change occurred.
+
+2014-07-28 Eli Zaretskii <eliz@gnu.org>
