I used getopt, not getopts (which on my system exists only as a bash
builtin). The reordering of the options (which I now see is specific to
gnu-getopt) was the entire motivation for my patch. This along with the
long option support is worth the dependency on gnu-getopt in my opinion.

Thanks for the clarifications regarding compatibility,
