23656	FormMixin.get_form's form_class argument should be optional	Simon Charette	nobody	"Just like we do with `SingleObjectMixin.get_object(queryset=None)` that defaults on `get_queryset()` we should make `FormMixin.get_form(form_class)` default on `get_form_class` to make overriding easier.

The provided patch introduces a backward compatibility issue for users that overrided `get_form()` on a `ProcessFormView` subclass and expected `form_class` to be `not None`. It could be addressed by removing the changes in `ProcessFormView.get()` and `ProcessFormView.post()`."	Cleanup/optimization	closed	Generic views	dev	Normal	fixed			Ready for checkin	1	0	0	0	0	0
