First, the default value for 1-k is documented as being 0, but is
currently being set to 1. (100%).  This causes all packets to be dropped
in the good state if 1-k is not explicitly specified.  Fix this by setting
the default to 0.

	Second, the 1-h option is parsed correctly, however, the kernel is
expecting "h", not 1-h.  Fix this by inverting the "1-h" percentage before
sending to and after receiving from the kernel.  This does change the
behavior, but makes it consistent with the netem documentation and the
literature on the Gilbert-Elliot model, which refer to "1-h" and "1-k,"
not "h" or "k" directly.

	Last, fix a minor formatting issue for the options reporting.
