A byte write to a replaced process.stdout.write or process.stderr.write
was boxed with the 'data' chunk helper, which answers a string while a
listener of a socket or HTTP response with setEncoding("utf8") runs. A
`process.stdout.write(buffer)` from such a listener reached the
replacement as a string. Node passes the Buffer it was given.
The stdio hook now boxes a byte write as a Buffer whatever listener is
running.
