YAML best practices for Ansible playbooks - tasks

This post is a follow-up to a recent discussion about YAML formatting for complex Ansible playbook tasks on the Ansible Project mailing list, and will also be appearing as part of Appendix B: Ansible Best Practices and Conventions in my Ansible for DevOps book on LeanPub.
