	* src/parse-util.c (parse_text_value_or_expr) : you do need to unref
	  the resulting style.  I forgot that autoformat generates formats.

	* src/format.c (style_format_unref) : unrefing NULL is ok.

	* src/cell.c (cell_set_text) : adjust to ref semantic change in
	  parse_text_value_or_expr.
	* src/commands.c (cmd_search_replace_do_cell) : ditto.
	* src/sheet.c (sheet_range_set_text) : ditto.
	(sheet_cell_set_text) : ditto.
	* src/xml-io.c (xml_read_cell_copy) : ditto.
