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. -- Matheus
