Um. Well, there isn't any such assumption in the protocol (and I'm agin
Peter's suggestion to put one in), but realistically I don't see us ever
allowing \0 in external-text-representation strings. It would break too
many things on both client and server sides, and the payback is too small.

The cases I can think of where you'd like to allow \0 are really binary
data, not text, and we now have respectably clean support for binary
I/O. So the need to allow it seems to me to have dropped way down, too.
