+{@Code "@IndexRangeFormat"} gives the format to use when a page
+number range, such as 5--8, is to be included in an index entry.
+Within it the symbols @Code "@From" and @Code "To" stand for
+the first and last page numbers respectively.  These will always
+be different when {@Code "@IndexRangeFormat"} is used; Lout knows
