so that commands like "sort -k 18446744073709551616" no longer fail merely because 18446744073709551616 doesn't fit in uintmax_t. The trick is that these fields can all be treated as effectively infinity; their exact values don't matter, since no internal buffer can be that long. * src/join.c (string_to_join_field): Verify that SIZE_MAX <= ULONG_MAX if the code assumes this. Silently truncate too-large values to SIZE_MAX, as the remaining code will do the right thing in this case. * src/sort.c (parse_field_count): Likewise. * src/uniq.c (size_opt, main): Likewise. * tests/join/Test.pm (bigfield): New test. * tests/sort/Test.pm (bigfield): New test. * tests/uniq/Test.pm (121): New test.
