xpipe (split input and feed it into the given utility)

The xpipe command reads input from stdin and splits it by the given
number of bytes, lines, or if matching the given pattern. It then
invokes the given utility repeatedly, feeding it the generated data
chunks as input. You can think of it as a Unix love-child of the
split(1), tee(1), and xargs(1) commands.
