Why does :q kill my emacs?

[guivho]

I've been using viper up to now and would like to use the visual and
inner word extensions provided by vimpulse.

So I downloaded http://www.emacswiki.org/emacs/vimpulse.el, installed
it in my lisp directory, and required it iso viper.

However, I am frustrated by the fact that now :q or :wq completely
kill emacs rather than the current buffer.

This is not the case when I stick to viper.

I have no idea how to figure this out, lease advise,

Guivho.
