	do not ignore write error for any output size
	The previous change was incomplete.
	While it makes emacs --batch detect the vast majority of stdout
	write failures, errors were still ignored whenever the output size is
	k * (BUFSIZ+1) - 4.  E.g., on a system with BUFSIZ of 4096,
	  $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
	      && echo FAIL: ignored write error
	  FAIL: ignored write error
	  $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
	      && echo FAIL: ignored write error
	  FAIL: ignored write error
	* emacs.c (Fkill_emacs): Also test ferror.  (Bug#9574)

	* xdisp.c (set_cursor_from_row): If the row ends in a newline from
	a display string, extend search for cursor position to end of row.
	(find_row_edges): If the row ends in a newline from a display
	string, increment its MATRIX_ROW_END_CHARPOS by one.  (Bug#9549)
	Handle the case of a display string with multiple newlines.
87 88 89
	(Fcurrent_bidi_paragraph_direction): Fix search for previous
	non-empty line.  Fixes confusing cursor motion with arrow keys at

	* xdisp.c (display_line): Record maximum and minimum buffer
	positions even if no glyphs were produced (e.g., by a zero-width
	stretch).  Fixes bug#9530 on a TTY.  Under word-wrap, don't record
	buffer positions that will be removed from the glyph row because
	they don't fit.
108 109 110
	(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.
111 112 113
	(reseat_at_next_visible_line_start): Undo the change made on
	2011-09-17 that saved paragraph information and restored it after
	the call to `reseat'.  (Bug#9545)

	reseat.

	* bidi.c (MAX_PARAGRAPH_SEARCH): New macro.

	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)

162 163 164
	* xdisp.c (set_cursor_from_row): Don't invoke special treatment of

	(selection_data_to_lisp_data): Assume incoming selection data are
	signed integers, not unsigned.  This is to be consistent with
	outgoing selection data, which was modified to use signed integers
	in as part of the fix to Bug#9196 in response to Jan D.'s comment
	in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11

	isnan: Fix porting problem to Solaris 10 with bundled gcc.
	Without this fix, the command to link temacs failed due to an
	undefined symbol __builtin_isnan.  This is because
	/usr/include/iso/math_c99.h #defines isnan(x) to
	__builtin_isnan(x), but the bundled gcc, which identifies itself
	as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
	a __builtin_isnan.
	* floatfns.c (isnan): #undef, and then #define to a clone of
	what's in data.c.
	(Fisnan): Always define, since it's always available now.
	(syms_of_floatfns): Always define isnan at the Lisp level.

	The previous code assumed that file offsets (off_t values) fit in
	EMACS_INT variables, which is not true on typical 32-bit hosts.
	The code messed up by falsely reporting buffer overflow in cases
	such as (insert-file-contents "big" nil 1 2) into an empty buffer
	when "big" contains more than 2**29 bytes, even though this
	inserts just one byte and does not overflow the buffer.
	(Finsert_file_contents): Store file offsets as off_t
	values, not as EMACS_INT values.  Check for overflow when
	converting between EMACS_INT and off_t.  When checking for
	buffer overflow or for overlap, take the offsets into account.
	Don't use EMACS_INT for small values where int suffices.
	When checking for overlap, fix a typo: ZV was used where
	ZV_BYTE was intended.
	(Fwrite_region): Don't assume off_t fits into 'long'.
	* buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.

	(Frecursion_depth): Wrap around reliably on integer overflow.

	Don't double-block input; malloc is safe here.  Don't assume 2**34
	- 4 fits in unsigned long.  Add an xassert to check
	XGetWindowProperty overflow.  Be more careful about overflow
	calculations, and distinguish size from memory overflow better.

	the loop as soon as EOB is reached; avoids infloops in redisplay
1250 1251
	when IT->position is set up wrongly due to some bug.
	Set IT->current to match the bidi iterator unconditionally.
1252 1253 1254 1255 1256 1257 1258
	(push_display_prop): Allow GET_FROM_STRING as IT->method on
	entry.  Force push_it to save on the stack the current
	buffer/string position, to be restored by pop_it.  Fix flags in
	the iterator structure wrt the object coming from a display
	property, as `line-prefix' and `wrap-prefix' are not ``replacing''
	properties.  (Bug#9284)
