The argument processing is zhack makes the assumption that getopt() will not permute argv. This isn't true for the GNU implementation of getopt() unless the optstring is prefixed with a '+'. In which case this is equivalent to setting the POSIXLY_CORRECT environment variable In addition, update the usage() and optstrings to reflect the existing supported options.
