+	Test/E01options.ztst: add KSH_ZERO_SUBSCRIPT option to handle
+	the currently default behaviour that $array[0] or $string[0]
+	is mapped to $array[1] or $string[1] if KSH_ARRAYS is not
+	in effect.  Now off by default; returns empty element or
+	causes error if used for setting.  Valid ranges that happen
+	to include zero are not affected.
