Make use of sed's line-handling ability

With flexible challenge outputI/O, it can pay to have input/output separated by newlines instead of any other character by taking advantage of sed's commands for handling lines (like D, N, n, G, H, P, s's m flag) instead of only being limited to s substitutions.

This can also open the opportunity for using D for looping instead of labels and goto, especially in sed versions that don't permit empty labels.
