cpio -vo | cpio -vi: wish I could distinguish messages

[Dan Jacobson]

There could be an option to add little arrows to the STDERR,
to distinguish the -v messages from each side:
find * | cpio -vo | ssh example.org cpio -idvm
a ->
b ->
c ->
1000 blocks
a <-
b <-
c <-
1000 blocks
Good even when jumbled.
