  /* Set getopt index back to initial value, so it will start with the
     first command line parameter again.  Also reset opterr to 1, so that
     error messages are printed by getopt().

     XXX - this seems to work on most platforms, but time will tell.
     The Single UNIX Specification says "The getopt() function need
     not be reentrant", so this isn't guaranteed to work.  The Mac
     OS X 10.4[.x] getopt() man page says

       In order to use getopt() to evaluate multiple sets of arguments, or to
       evaluate a single set of arguments multiple times, the variable optreset
       must be set to 1 before the second and each additional set of calls to
       getopt(), and the variable optind must be reinitialized.

           ...

       The optreset variable was added to make it possible to call the getopt()
       function multiple times.  This is an extension to the IEEE Std 1003.2
       (``POSIX.2'') specification.

     which I think comes from one of the other BSDs.

     XXX - if we want to control all the command-line option errors, so
     that we can display them where we choose (e.g., in a window), we'd
     want to leave opterr as 0, and produce our own messages using optopt.
     We'd have to check the value of optopt to see if it's a valid option
     letter, in which case *presumably* the error is "this option requires
     an argument but none was specified", or not a valid option letter,
     in which case *presumably* the error is "this option isn't valid".
     Some versions of getopt() let you supply a option string beginning
     with ':', which means that getopt() will return ':' rather than '?'
     for "this option requires an argument but none was specified", but
     not all do. */
