formset.is_bound returns False for ModelFormsets created with queryset as argument

[Jannis Vajen]

When a Modelformset is instantiated via a queryset, its is_bound attribute returns False although all of its forms are linked to instances of the queryset. This seems a bit odd to me because formset and forms are bound as soon as the Modelformset is instantiated via data (i.e. request.POST).

>>> from django.forms.models import modelformset_factory
>>> from models import Testobject

>>> TestFormset = modelformset_factory(Testobject)
>>> formset = TestFormset(queryset=Testobject.objects.all())

>>> formset.is_bound 
False
>>> formset.forms[0].is_bound
False
>>> formset.forms[0].instance
Testobject object

This is correct behavior - instantiating ModelFormSet with a queryset is the equivalent of supplying initial to a Form which also isn't bound in that case.
