(This is no longer very Lisp-related, so I'll just write this
additional article.)

They don't see ^D, they see the current input line, without any
terminting character. (If the line is empty, there will be zero
characters, interpreted as EOF.) For example, here's a Lisp session
where I used ^D to enter three input lines:

This is SBCL [...]
* 42
42
* (defun foo () (quit))
FOO
* (foo)[Exit]
.
