Hopefully I am not wasting your time by responding to an old thread, but
I figured this out and wanted to post it for posterity.

The answer is that it is not about handling _options_ in order, but that
we need to handle pseudo-options in order with non-options, like:

  foo --not bar

Stepping through the options with parseopt will just cover dashed
options, but we handle non-option arguments later. So we have to handle
the pseudo-arguments like "--not" at the same later time.

So there's nothing interesting to clean up or fix here.
