The buffering is a feature of FILE* streams and is done in libc on both
sides.  So you effectively get the larger of the two buffers set by both
sides on the reading side (ordering the sizes none < line < full).

If the writer only sends the data to the pipe in full blocks there's
nothing you can with it on the reading side.

At least that's how I understand it.
