35035	BaseFormSet should use Form's default_renderer before defaulting to get_default_renderer().	Christophe Henry	nobody	"When creating a `BaseFormSet` using a subclass `Form` that defines `default_renderer` to a custom, it's a bit disturbing that the `BaseFormSet` does not try to use this renderer before defaulting to `get_default_renderer()`. This requires the user to always explicitely specify the renderer when subclassing `BaseFormSet` or using `formset_factory`, which is error prone.

I propose the following: when instanciating a `BaseFormSet`, if `self.renderer` is `None`, instanciate an empty form with `self.empty_form` (the form's `default_renderer` may be a property) to get the form's `default_renderer`. If this one is `None`, default to `get_default_renderer()`."	Cleanup/optimization	closed	Forms	4.2	Normal	wontfix		David Smith	Unreviewed	0	0	0	0	0	0
