in reply to complaint: always testing defined()

The construction I use (after invoking GetOpt to return $flag) is:

            $flag = 0 if !$flag;

I'm certain there are better ways (and I look forward to reading about them).

    $flag||=0; is faster :)

    This is one of the rare instances where I'd find unless more acceptable 
    $flag = 0 unless $flag;
