I think it is a fine enhancement. It will probably help someone when
starting out with stap and getting the option arguments wrong. If you
have time to do it generically please do. But if you just fix it option
at a time that seems fine too. Assuming it isn't really lots of
duplicate code, which it doesn't seem to be, just one line per option
processed.

Thanks,
