 Hi Jilles!
     We discussed this earlier over IRC, but just to reiterate some points...

     It's fine if hexdump is a start's this trend and core agrees,
 because it's been widely ported to other packages outside of FreeBSD,
 like util-linux-ng, etc. So, I'm just taking all of the issues and
 resolving them so that hexdump, et all has higher quality than it
 currently does, because QA in hexdump has been neglected in the past
 and it's a handy tool that should be more robust. Plus, it looks like
 a bad mark on the project when a piece of software has so many issues
 with segfaults, et all.
     If warnx(3) is appropriate for now until the rest of the commands
 in /bin and /usr/bin conform to the new standard (if that's the way we
 want to go longterm), I'll gladly change the patch to warnx(3).

     This is done because hd / od are hardlinks created when make
 install is run for hexdump, and they share a TON of common code (only
 the values set by the different usages differ -- the rest of the logic
 is equivalent).
