Sigh. I did od because posix said to
(http://pubs.opengroup.org/onlinepubs/9699919799/utilities/od.html) and
did hexedit because it was interactive. (Although I broke out the
draw_line() logic thinking I could genericize stuff and maybe reuse code
here...)

Now here's a third that doesn't share code with either of the first two.
It's small, it looks simple, and it's the third implementation of the
same stuff...

That's why it went on the todo list instead of immediate merging,
anyway. I should at least throw it in pending though...
