Which shells have you confirmed this with?

You might not want to say "never". Using redirection is one way I've
overcome programs with large file problems. Streams of data don't use
seeks, and therefor usually don't have file size limitations. If a
program opens a file itself and uses 32 bit calls, but also can be told
to use stdin/out, using stdin and out can solve the problem.

Most unix programs try not to make assumptions like this, and I've never
run into this "feature" in a bsd or linux (or solaris?).
