	* src/commands.c (cmd_search_replace_do_cell) : Adjust to ref
	  semantics change.

	* src/number-match.c (format_match) : do not add a ref to the
	  resulting format.

	* src/sheet.c (sheet_cell_set_text) : no need to unref anymore.
	(sheet_range_set_text) : ditto.

	* src/cell.c (cell_assign_value) : ref before unref.
	(cell_eval_content) : Use a simplified assignment to avoid refing and
	  unrefing the formats.
	(cell_set_text) : cleanup reference handling.
