like it will be approved. Also add --check=quiet, --check=silent
as long aliases, and --check=diagnose-first as an alias for -c.
* doc/coreutils.texi (sort invocation): Document this.
Also, mention that sort -c can take at most one file.
* src/sort.c: Implement this.
Include argmatch.h.
(usage): Document the change.
(CHECK_OPTION): New constant.
(long_options): --check now takes an optional argument, and is now
treated differently from 'c'.
(check_args, check_types): New constant arrays.
(check): New arg CHECKONLY, which suppresses diagnostic if -C.
(main): Parse the new options.
* tests/sort/Test.pm (02d, 02d, incompat5, incompat6):
New tests for -C.
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.

in `sort' and `comm'. POSIX.2 requires that we consider newline,
but this is a bug in the spec and the bug will likely be fixed.
Update tests `use-nl' and `11d' to reflect this change.
