25320	ManyToManyField.null returns True on master (upcoming 1.9), False on 1.8.	Anssi Kääriäinen	nobody	According to report on PR https://github.com/django/django/pull/4241#issuecomment-135492016 we unintentionally changed the flag's value in 1.9. The null flag for ManyToManyField isn't that well specified to begin with (does it mean can the joins generate NULL values (True), or can the returned list be None (False)?). But I don't see any reason to change the flag's value in 1.9, so fix for the upcoming 1.9 release seems appropriate.
