No back validate

Here's an undocumented option for your Chaos Tools form wizard (not sure if it's in the D6 code): 'no back validate'.

It prevents validation of the current form when you click the back button which means you can use #required fields and prevent Drupal from insisting the user fills them in before going back through the form.

You can either put it in the root level of the $form_info array, or in one or more of the form description entries. The former means that the back button will always prevent validation, with the latter you can control which forms do and don't have validation on the back button.
