According to POSIX, -ok is supposed to be like -exec, except for the fact
that it prompts and read stdin. By that interpretation, it is a bug that find
redirects stdin of the child process of -ok from /dev/null; it should let the
child see the same stdin. If find's stdin is not seekable (such as a pipe),
then behavior is already unspecified; so it is okay for find to continue using
stdio to read prompts, as long as it resets the seekable fd back to the
newline that ended the response to the prompt, even though this means that
child processes will inherit piped stdin in an unknown state.
