	* src/gnumeric-sheet.c (gnumeric_sheet_key_mode_sheet): Return the
	result of gtk_widget_event() if we get to the switch's default
	case.
	(gnumeric_sheet_key): Return FALSE in the default case, since we
	did nothing there.

	* src/workbook.c (open_cmd): If the file-open dialog was
	cancelled, it will return NULL.  Take this into account.
