RangeFull for-loop iteration fails because of IntoIterator

Browse source 
Saying that "[for-loop iteration] fails because .. has no IntoIterator
impl" is more direct than saying "...no Iterator impl" because for loops
sugar into IntoIterator invocations. It just happens that the other
Range* operators implement Iterator and rely on the fact that
`IntoIterator` is implemented for `T: Iterator`.
