Add more support for POSIX 1003.1-2001, which requires removal for
support of obsolete "-N" option syntax in expand, head, fold,
split, tail, unexpand, uniq, and which prohibits options with
optional arguments in od and pr.
(main): Check for obsolete options.
(main): Fix bug: -- -N was treated as -N --.
