I have seen people complain (based on the man page) that GNU cat doesn't support -u, although POSIX requires it. Yeah, they could have read the source or tested the program. It is true though that the documentation is somewhat ambiguous. The attached patch addresses this tiny problem. Roger -- Hedonist for hire. No job too easy.
