I didn't realise the autodetector could handle that. Looking more
closely, it looks like I have more of an edge case:

App B has a model with a FK to a model in app A

App A has a model with a ManyToMany field 'through' a model in app B.
(It's actually added that way for the sake of the admin for the models
in app A).

So it isn't the straight-forward A has FK to B. It might not be worth
fixing the autodetector for this, as fixing the migrations is relatively
easy. But I think fixing the infinite loop is another matter, and I'll
go ahead and backport that.

Thanks for the input,
