Typing it into Emacs is different. When you type it into a shell, the
terminal driver intercepts it before it gets passed through to the
program underneath and does something else with it (or may do...you
can change it with `stty', make some other key, or no key at all, have
that functionality; whatever). But Emacs will just pass the character
through to Lisp (which I expect treats it as whitespace)
Typing it on a non-empty line in a shell just does something like
"force-output" (only in the other direction, of course)

As expected. But "34 ^D" should give you 34
[Except in CLISP, I guess, since that uses readline...]
