1037	ManyToMany should have support for deleting a single relation	hugo	nobody	Currently you would have to get the list of relations for a ManyToMany field, remove the relation you want to delete and set the list of relations new. With large numbers of relations this can be inefficient (actually it's inefficient with smaller numbers, too, but might just not be such a problem). I think it would be a good idea to have a delete_<field> as a complementary of the existing add_<field> method.	enhancement	closed	Core (Other)		normal	invalid	feature_request		Design decision needed	0	0	0	0	0	0
