> If a zero-length file is sent/received via SCP then we run the risk of using a zero-length
copy buffer size - in which case, the copy loop may run forever. This can also happen if using
SCP to copy special files - e.g., _/proc/mounts_, _/dev/xxx_ which seemingly have zero size,
but if opened and read do have content.
