Now that we've already got "hexdump -C", make calling the command "hd"
having the same effect, and install a link for this. There is
historic precedence for the command hd(1) (with roughly that output
format) in Xenix, SCO, and a few SysV's that tooks the idea.
Also, added a couple of spaces to the -C format to make the output
better readable.
