tail: Allow repetitive or contraditory options
Unlike its GNU counterpart, our tail(1) has always errored out if given
repetitive or contradictory options, even prior to Keith Bostic's 1991
reimplementation. There is no good reason to continue to do so, not
even tradition, since many other commands (including head(1)) simply
apply the rightmost option in cases like this.
