Carlos' patch uses a function that takes and returns indexes (ie
integers)

Good point. We could probably handle that by adding a page type for
progress pages, and then skipping those when going back.

There will be a page type to mark pages as confirm page (for complicated
nonlinear or looping wizards, it can be necessary to have a confirm page
in the middle of the sequence). By default, the last page will be
handled as a confirm page.
