usr: xxd - hex dump a file or stdin
Eight bytes per line rather than the usual sixteen: offset + 8 hex pairs +
the ASCII column is 38 of the terminal's 40 columns, where 16 would wrap
every line and make the dump unreadable. -c overrides it.
No -s (skip): there is no seek syscall, so it streams from the start - the
same reason tail(1) has to keep a ring.

blk(1) could already peek at raw disk blocks; nothing could look inside a
file. Verified against known bytes, from stdin, with -c, through a pipe, and
on a missing file.
