Going a bit off topic here, but I suspect the reason split adds empty
strings is because it is matching the 8 characters, splitting there, but
because you are capturing them, puts the delimiter back in the array it as
well. The gap between the 8 characters is nothing, thus "". I guess that if
you split(/\w{8}/) you'll get nothing because there will be nothing left
after removing the delimeter (unless the string isn't of length 8n, n is an
integer.)
