	* src/fn-math.c (callback_function_sum): Do not try to be smart
	about string content.  Let the smartiness to other layers.
	(gnumeric_average): Handle division by zero on average routine.

	* src/number-match.c (create_option_list): Small bug fix:  First
	translate, then move the pointer ahead.

	* src/cell.c (str_trim_spaces): Trim space routine was removing
	everything after the first space instead of removing only the
	trailing space.
	(cell_draw): Free the original string, not the modified copy.

	* src/sheet.c (sheet_set_text): Test if the format has been
	manually set by the user before trying to do format matching.

	* src/cell.h: New flag: CELL_FORMAT_SET, used if the user has
	manually specified a format. FIXME: This information should be
	saved and loaded.

	* src/cell.c (cell_set_format): Set the CELL_FORMAT_SET flag
