mcedit with emacs keybindings

[Paul Seelig]

Hi!

I'm using both emacs and mcedit with emacs keybindings on a regular
basis. And regularily it happens to me that when i'm editing a text in
mcedit and i press ctrl-g it simply exits without saving any changes.
That's particularily annoying when you've written quite a lot without
manually saving the file used... :-/

This is no emacs behaviour at all and should definitely be changed.
Emacs doesn't exit on ctrl-g and mcedit should behave the same.
