The manual and the code were both not correct on this topic. The
minimum length of a port buffer is 0 for output ports and 1 for input
ports (because we have to support peek-char). I added some explanation
to the manual and fixed the argument checking in the code.

Sorry, I don't know how to fix this without completely obfuscating the
source code. This is either some TeX obscurity I don't understand or a
bug in tex2page. I put it on my TODO list.
