17077	deleting empty row in formset	Sergiy Kuzmenko	nobody	"If in a formset user marks empty row for deletion, form validation succeeds but retrieving cleaned_data fails. How to replicate:

{{{
>>> from django import forms
>>> from django.forms.formsets import formset_factory
>>> class ArticleForm(forms.Form):
...     title = forms.CharField()
...     pub_date = forms.DateField()

>>> ArticleFormSet = formset_factory(ArticleForm, extra=1, can_delete=True)
>>> data = {
...     'form-TOTAL_FORMS': u'2',
...     'form-INITIAL_FORMS': u'0',
...     'form-MAX_NUM_FORMS': u'',
...     'form-0-title': u'Test',
...     'form-0-pub_date': u'1904-06-16',
