It's not a good example, because bash disables the canonical mode. When you type ^D this happens:

  read(0, "\4", 1)                        = 1

(And then bash ignores the read EOT character.)

Author here. You're correct. I've added a footnote to that part now. I think it still illustrates the point so I've left the main text alone.
