cogito-0.18.2: Portability problems with utility arguments

Hi!

I just updated the NetBSD pkgsrc package for cogito[1] to 0.18.2.
Currently there are three patches in pkgsrc for cogito, all of
them submitted for inclusion by Anthony Mallet, see
	http://www.NetBSD.org/cgi-bin/query-pr-single.pl?number=35020
	http://www.NetBSD.org/cgi-bin/query-pr-single.pl?number=35147

Here are the patches and the explanations.

patch-ab:
xargs on NetBSD does not know "--null", it does however know
the equivalent "-0".

patch-ac, patch-ad:
fmt on NetBSD does not know "-s". These patches just remove
the "-s". I'm not sure how to fix this, really.

Please include patch-aa, and if you find a way to work
around the "fmt -s", I'd appreciate it.

Cheers,
 Thomas

P.S.: Please cc me on replies, I'm not on this list.
