Oh I agree. I was merely pointing out that the likelihood of one is no
more than the other.

In fact, I _have_ worked on systems (in the 90s, admittedly) where
intr was mapped to the "Delete" key. I've never (to my knowledge)
worked on a system where EOF was mapped to anything other than CTRL-D
in a command-line context, although I can see that emacs obsessives
might want to have configured their readline that way, which would
stomp all over ctrl-D.

It also occurs to me that if someone has just typed quit<cr> or
exit<cr> space at the start-of-line should not be a problem for
Ctrl-D, because the buffer is empty.

I still think it (Ctrl-D on *nix, Ctrl-C on windows) is the best of a
bad bunch, to be honest.
