I am going to weigh in here. Denis is absolutely correct. It is an official binding and convention in emacs, and I believe xemacs.
C-h is sacred. It has a bunch of functionality behind it tied in with prefix keys. This means that in creating a map, and binding it to a prefix key, when you hit: <prefix-key>, C-h it will list all the bindings for that key's map. As a very practical example, I use F5 for various org-mode functionality. This is accomplished by defining F5 as a prefix key, and binding a keymap I populated with various bindings to that key. Now whenever I forget (frequently) what I had bound to what I just hit F5,C-h and all the bindings are displayed. And this holds for C-c. If I hit C-c,C-h it is because I want to see what the bindings are for the current mode. I and many other emacs users would be seriously thrown, not to say upset, if this functionality was changed. The C-h binding is very important for discoverability, and I think it is a very, very bad idea to bind it to anything. Just my 2 cents worth.
