+        they don't fit.
+        (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
+        column is beyond frame width: don't subtract 1 "pixel" when
+        computing width of the stretch.
+        (reseat_at_next_visible_line_start): Undo the change made on
+        2011-09-17 that saved paragraph information and restored it after

+2011-09-18  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Fix minor problem found by static checking.

+        initialized, to pacify gcc -Wuninitialized.
+
+        * fileio.c: Report proper errno when syscall falls.
+        (Finsert_file_contents): Save and restore errno,

+
+        * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
+        (bidi_find_paragraph_start): Search back for paragraph beginning
+        at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
+        (bidi_move_to_visually_next): Only trigger paragraph-related
+        computations when the last character is a newline or at EOB, not
+        just any NEUTRAL_B.  (Bug#9470)
+
+        * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
+        truncated lines if point is covered by a display string.  (Bug#9524)
+
+2011-09-16  Paul Eggert  <eggert@cs.ucla.edu>
