+       * Version 5.0.90.
+
+       Begin to address this comment: What if someone wants to
+       extract the 1,000,000-th field of some huge input file?
+       The first step is to rearrange things so that the values
+       in the printable_field array are all 0/1 rather than 0/1/2.
+       * src/cut.c (RANGE_START_SENTINEL): Remove.
+       Store range-start indices in a hash table, rather than
+       overloading the `printable_field' array.
+       (range_start_ht): New global.
+       (hash_int, hash_compare_ints, is_range_start_index): New functions.
+       (print_kth): Use is_range_start_index; don't test printable_field.
+       (set_fields): Detect overflow.
+       (set_fields): Insert each range-start index into range_start_ht.
+       (main): Call set_fields only once, and only after
+       output_delimiter_specified and (if required) range_start_ht have
+       been defined.
