There is an additional problem with PyBuffer_ToContiguous(): Suppose 'view' is multi-dimensional, C-contiguous and initialized according to PyBUF_ND, i.e. view->shape != NULL but view->strides == NULL. Now if PyBuffer_ToContiguous() is called with 'F', PyBuffer_IsContiguous() returns false and view->strides will be accessed. This means that incomplete buffer information will have to be reconstructed like it is done in the 3.3 memoryview.
