	* src/sheet-control-gui.[ch] (scg_rangesel_cursor_extend,
	  scg_take_focus): new functions to wrap direct calls to gsheet.

	* src/sheet-control-gui.c (sheet_view_destroy): Yield focus if we
	have it.

	* src/workbook-control-gui.c (wb_control_gui_focus_cur_sheet): Use
	scg_take_focus instead of gtk_window_set_focus.
	(yield_focus): Remove. sheet_view_destroy now takes care of this.
	(wbcg_sheet_add): Do not attach yield_focus.

	* src/item-grid.c (cb_extend_expr_range): Use
	scg_rangesel_cursor_extend instead of gnumeric_sheet version.
