Missing document separators when Kubernetes documents have been added/removed

[ajhall]

When comparing a list of Kubernetes manifests against each other and some documents have been added or removed, there are no document separators in the "documents removed"/"documents added" output, so all the manifests run together.

Example:

# a.yaml
---
apiVersion: v1
kind: Namespace
metadata:
  name: a
---
apiVersion: v1
kind: Namespace
metadata:
  name: b

# x.yaml
---
apiVersion: v1
kind: Namespace
metadata:
  name: x
---
apiVersion: v1
kind: Namespace
metadata:
  name: y

$ dyff between -ib a.yaml x.yaml

(file level)
  - two documents removed:       ---
    ---                          apiVersion: v1
    apiVersion: v1               kind: Namespace
    kind: Namespace              metadata:
    metadata:                    │ name: x
    │ name: a                    apiVersion: v1
    apiVersion: v1               kind: Namespace
    kind: Namespace              metadata:
    metadata:                    │ name: y
    │ name: b

I would expect it to look something like this instead:

  - two documents removed:       ---
    ---                          apiVersion: v1
    apiVersion: v1               kind: Namespace
    kind: Namespace              metadata:
    metadata:                    │ name: x
    │ name: a                    ---
    ---                          apiVersion: v1
    apiVersion: v1               kind: Namespace
    kind: Namespace              metadata:
    metadata:                    │ name: y
    │ name: b

dyff between -ib  a.yaml x.yaml 

metadata.name  (v1/Namespace/y)
  ± value change
    - b
    + y

metadata.name  (v1/Namespace/x)
  ± value change
    - a
    + x
