POSIX requires support for simultaneous -f and -i, in either order, so we
can't error out there. But since -n is an addition, we can error out
depending on -f or -i, if that makes more sense than overriding.
Again, since we are modeling after the fact that FreeBSD provides it, what
is the behavior on that platform when you mix-n-match -fin?
