Remove redirection_is_to_real_file This was previously required so that, if there was a redirection to a file, we would fork a process to create the file even if there was no output. For example `echo -n >/tmp/file.txt` would have to create file.txt even though it would be empty. However now we open the file before fork, so we no longer need special logic around this.
