What if it's a non-*ix machine and a non-VMS machine, and it just happens to
give the usual login: -prompt?  Remember that you connected to this machine
by accident and it could be anything.

Assuming for a moment that it is a *ix machine, ^D is the worst possible
thing you can type at that point.  In *ix ^D means that you have finished
typing input and YOU ARE SATISFIED WITH THE INPUT.  When you type ^D to the
shell to logout, you certainly don't mean that everything you've done was
wrong; you just mean that you're done.  ^D means the same thing when used
with programs running in the shell.  Thus by typing ^D at the login: prompt,
you are admitting that you intended to illegally connect to the computer,
and that after being partially successful, you decide to take a break and
celebrate.

The proper character to type to a mistaken login is ^C, which means that 
you have made a mistake and you want to discard everything.  However, if you 
try this, you will find that nothing seems to happen.  And that is because
the appropriate authorities have been notified at that point, and you should
just sit back and not move and wait for them to take you away.
