Subject: Add more support for POSIX 1003.1-2001, which requires removal for
X-Git-Tag: TEXTUTILS-2_0_21~117
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3c25a62eb8c076596fcda45eb115ace186c41559;p=platform%2Fupstream%2Fcoreutils.git

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.

(usage): Document this.
(main): Check for obsolete options.
(shortopts): New constant.
(main): Use -1, not EOF, for getopt_long.
