6197	Please add formfield_callback arg to newforms.models.ModelFormMetaclass.__new__().	guido@…	nobody	"I've run into a use case where I want to subclass the metaclass in order to provide a different way to map models to form fields.  Right now I have to copy all of ModelFormMetaclass.__new__() in order to override the formfield_callback argument in the call to fields_for_model() in __new__().

I'll attach a patch too."		closed	Forms	dev		fixed			Unreviewed	1	0	0	0	0	0
