Quit help for someone new to Emacs

[Zhu Zihao <all_but_last@163.com>]

Well, it's not a joke. I found Vim will give a hint for new user how can they
really quit Vim when they try to press "C-c".

I know there's detailed message in splash screen describes that how to quit. But
if a new user use Emacs to open a file directly(e.g. run "emacs .bashrc" in
bash). They can't see this useful message.

For Emacs, "C-c" is preserved for user bindings. So it's always empty for a
Emacs without any user configuration. IMO, it maybe useful to pop a message
"Press 'C-x C-c' ('C-' means Ctrl-) to quit Emacs" in echo area when someone hit
"C-c" frequently. And no doubt that this feature can be controlled via a Lisp
variable.

What's your opinions?
