  Ah, I understand. s6-tai64nlocal isn't *printing* line per line, it
is *reading* line per line. It buffers its input until it gets a full
line, then converts the timestamp at the beginning, if any, then puts
the converted line into the output buffer, and flushes that buffer
before going back to reading.

  Yes, it is expected. It makes scanning for a timestamp much easier
and straightforward. Compare s6-tai64nlocal.c and tai64nlocal.c.
