This list contains a template for the tests.
Two 'foreach' loops below add the '{IN/OUT}' hash entries
of typical coreutils tests, adds single-quotes around the sed program,
and adds the --debug command line option.
NOTE: test names with "_" character will be checked with NULL input,
but not with non-empty input (eg. to avoid executing external programs).
