several reasons for my preference:

- xeno-test is already cluttered with options, many of which propagate 
down to tests
- as more tests are added, more option-clashing is inevitable.
    this makes pass-downs more complicated.
- prog-specific options isolate us from option clashes / churn
- assuming -a <prog>,
    need to handle multiples on line (I havent done that with shell getopts)
    I have to wonder if all shells have uniform getopt behavior -
       we want to work on bash, sh, ash, dash ...
- I get to duck the manpage update ;-)
