Only annotate if borrow is returned. Error now correctly checks whether the borrow that does not live long enough is being returned before annotating the error with the arguments and return type from the signature - as this would not be relevant if the borrow was not being returned. 2018-09-19 02:48:47 +02:00			`fn foo(x: &u32) -> &u32 {`
