Keep indentation of arrays during update

[felipecrs]

Please describe your feature request.

Sorry, I searched but I did not find any similar issue.

Consider a YAML file like:

apiVersion: v2
appVersion: "0.1.0"
description: A Helm chart
name: mychart
version: "0.1.0"
dependencies:
- name: anotherchart
  version: ">0.0.0-0"

And what happens is:

$ yq '(.dependencies[] | select(.name == "anotherchart") | .version) |= "1.1.1"' Chart.yaml
apiVersion: v2
appVersion: "0.1.0"
description: A Helm chart
name: mychart
version: "0.1.0"
dependencies:
  - name: anotherchart
    version: "1.1.1"

- - name: anotherchart
-   version: ">0.0.0-0"
+   - name: anotherchart
+     version: "1.1.1"

Describe the solution you'd like

I want the output to retain the original indentation of the array, i.e.:

apiVersion: v2
appVersion: "0.1.0"
description: A Helm chart
name: mychart
version: "0.1.0"
dependencies:
- name: anotherchart
  version: "1.1.1"

Describe alternatives you've considered
I haven't found any way around it.

Yep this is a known and documented issue with the underlying go-yaml parser :(

Thank you!

This is quite a dealbreaker when using version control where fill diffs are important.
