Patch from Shaun Jackman:

More to the point, this patch uses the same regex that sed.c is already using
(opportunity to suck in less library code), and even building a dynamically
linked busybox with just expr the result is a slightly smaller binary (by 94
bytes, I dunno what nm --size-sort has to say about it because I didn't build
with debug info, since that changes the binary size a lot by disabling
optimization...)
Your mileage may vary. Handle with caution. Do not taunt happy fun ball.
