I'm not sure what you mean. The current behavior is to return the line
immediately. When readline reads the tty eof character, it sets rl_done
and breaks out of the character reading loop. readline() ends up returning
a NULL pointer in this case. It's up to the calling application to react
to the NULL pointer.
