works well for me, too. another thing i'd love to see is the -P flag becomming
interactive. also i think the -H option should really be documented along with
the other flags. i've seen quite a lot of people not finding the right section.
documenting a flag after the BUGS section is really non intuitive, no matter,
if the -H flag is freebsd specific or not. it should really be added to the
OPTIONS and INTERACTIVE MODE sections.

cheers.
