client-gen does not generate the content of typed/<group>/<version>/<group>_client.go / typed/<group>/<version>/generated_expansion.go when there is no new line between the // +genclient tag and the next struct.

How to reproduce:

works

// +genclient
// +k8s:deepcopy-gen:interfaces=k8s.io/apimachinery/pkg/runtime.Object

type Foo struct {

fails

// +genclient
// +k8s:deepcopy-gen:interfaces=k8s.io/apimachinery/pkg/runtime.Object
type Foo struct {
