I don’t think that is true. I tried grepping for what I need in a very small terminal and still got the correct result.

I tried overriding stdin, stdout and stderr to pipes and calling setsid() in the forked child process to detach from the controlling terminal, but it still detected the terminal size. Anyway, the "ww" option of ps overrides this behavior.
