I see. I have no objections to that.
My initial implementation also worked like this.

I did it that way because someone explicitly requested that
POSIX mode not be affected in any way and this would
theoretically stop the user from sourcing a file named `-i`.

If that's not a problem then there's no reason not to
recognize the option even in POSIX mode.
I'll make it so in the v3 patch set.
