IIRC, the end result of the discussion was that no consensus could be
reached on whether it was better to reorder or not to reorder, so CGF had to
make a ruling, and he ruled not to reorder.

Reordering can be enabled by setting POSIXLY_INCORRECT_GETOPT in the
environment, but because getopt is statically linked, this only works for
programs rebuilt since this change was made, and many haven't been yet.
