11804	Filterspec fails to remove __isnull when __exact passed	marcob	nobody	"I have a link for my users that open a changelist page with a user!__id!__isnull=True. That changelist has also a list filter on my users. When a user is chosen, the filter !__isnull is not removed.

I remove !__isnull when !__exact is passed (in remove or in new_params)"		new	django.contrib.admin	1.1				marcoberi@…	Unreviewed	1	0	1	0	0	0
