Fix zhack argument processing 

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.
