WizardView template documentation incorrect

[Bradley Ayers <bradley.ayers@…>]

​https://docs.djangoproject.com/en/dev/ref/contrib/formtools/form-wizard/#creating-templates-for-the-forms has sample HTML showing how a wizard could be rendered.

However the this code is missing type="submit" on the buttons.

<button name="wizard_prev_step" value="{{ wizard.steps.first }}">{% trans "first step" %}</button>
<button name="wizard_prev_step" value="{{ wizard.steps.prev }}">{% trans "prev step" %}</button>

Actually this is also a problem in the template, not just in the doc: https://code.djangoproject.com/browser/django/trunk/django/contrib/formtools/templates/formtools/wizard/wizard_form.html?rev=16616#L14

Back to 'Accepted' as it needs more than just a trivial doc patch.

I think this is also a bad example on how to "go back". If you have a form that has a file field, and you choose a file to upload, and then click "back", it's going to submit the form, meaning your file will be uploaded. Although there's no other way to do it using WizardView, I think this limitation should be made more obvious (and urge developers to use NamedUrlWizardView instead which allows you to just use a hyperlink to the previous form.)

I've incorporated #17153 into this patch.

Fixed #17152 -- Fixed a few anomalies in the contrib.formtools documentation and templates. Thanks, Bradley Ayers.
