Alter action for Cancel button on checkout page

Since you can change the redirection of Add to cart in the cart settings, you probably want to be able to change redirection of Cancel button on checkout page.

A typical example is when you want to skip the cart page and directly go to the checkout one (if your website sale only one product for instance). So far the Cancel button brings you back to the cart page and you can't change it.

Need a way to specify a redirection for the Cancel button and an option to make it directly empty the cart.
