Hi Merrill,

first of all, please configure your mail (or news client) to:
- preserve threads
- do line wrapping

Both issue makes reading a bit harder.

"bombs" is fairly inexact. You mean your monitor explodes? Or something

- specify the exact behaviour you see
- provide minimal complete example which exposes the behaviour

The expected behaviour on unknown options is to throw an exception. Do you
have a "catch" statement?
