Transforms from/to Lines.item.
Return a transform that converts a stream of arbitrary strings to a stream of lines. If the input terminates without a newline, the trailing string is still considered a line.
Return a transform that converts a stream of lines to a stream of pairs of lines. It is considered an error if input ends with an odd number of lines.
Return a transform that output Line.items to strings (in other words a buffer with the lines plus their end-of-line character).
