+        Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
+        * editfns.c: Rewrite current-time-zone so that it invokes
+        the equivalent of (format-time-string "%Z") to get the time zone name.
+        This fixes a bug when the time zone name contains characters that
+        need converting from the system time locale to Emacs internal format.
+        This fixes a shortcoming that I introduced in my 1999-10-19 patch:
+        that patch fixed format-time-string to do the conversion, but
+        I forgot to fix current-time-zone.
+        (format_time_string): New function, containing most of
+        what Fformat_time_string used to contain.
+        (Fformat_time_string): Rewrite in terms of format_time_string.
+        This doesn't change this function's behavior.
+        (current-time-zone): Rewrite to use format_time_string.
+        This fixes the bug reported by Michael Schierl in
+        <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
+        Jason Rumney's 2007-06-07 change worked around this bug, but
+        didn't fix it.
+        * systime.h (tzname, timezone): Remove no-longer-used declarations.

+        * xdisp.c (start_display): If the character at POS is displayed
+        via a display vector, reset IT->current.dpvec_index to zero.
+        (try_window_reusing_current_matrix): If a line ends in a display
+        vector or the next line starts in a display vector, continue
+        redrawing the window even though the character position of
+        start_row was reached.

+        with nobreak-char-display too.

+
+        Fix part 3 of bug#9771.
+        * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
+        (bidi_resolve_neutral): Don't enter the expensive loop looking for
+        non-neutral characters if the current character is a paragraph
+        separator (a.k.a. Newline).  This avoids running the same
+        expensive loop twice, once when we consume the preceding newline
+        and the other time when the line actually needs to be displayed.
+        Avoid the loop when we see neutrals on the base embedding level
+        following a character whose directionality is the same as the
+        paragraph's.  This avoids running the expensive loop when a line
+        ends in a long sequence of neutrals, like control characters.
+        Add assertion against STRONG_AL type.  Slightly rearrange code
+        that determines the type of a neutral given the first non-neutral
+        that follows it.
+        (bidi_level_of_next_char): Set next_en_pos to zero when
+        invalidating its info.

+
+        * xdisp.c (push_display_prop): Determine whether to record string
+        or buffer position by IT->string, not by IT->method.  Allow
+        GET_FROM_DISPLAY_VECTOR as IT->method on entry.  (Bug#9771, part 4)
+        (move_it_vertically_backward): Don't look for character position
+        immediately after the newline when in a continuation line.
+        (Bug#9771, part 1)
