Thanks --  I learned about this after creating the bug report.

Before:

    # Ref. https://github.com/paluh/ansible-augeas
    - hosts: all
      tasks:
        - action: augeas commands='ins ForwardAgent before "/files/etc/ssh/sshd_config"
                                   set "/files/etc/ssh/sshd_config/ForwardAgent" "yes"'

        - action: augeas commands='
            ins ForwardAgent before "/files/etc/ssh/sshd_config"
            set "/files/etc/ssh/sshd_config/ForwardAgent" "yes"
            '

After:

    - hosts: all
      tasks:
      - augeas:
          commands: |
            set /files/etc/lvm/lvm.conf/backup/dict/backup_dir/str  /var/backups/lvm/backup
            set /files/etc/lvm/lvm.conf/backup/dict/archive_dir/str /var/backups/lvm/archive

I'm 99% sure I tested all syntaxes and confirmed they all edited lvm.conf correctly.

Since the "after" notation works, is easier to read, and is already
indented correctly by yaml-mode, I no longer care about this ticket.

Thanks, I did not know about this.  I had a quick look.

Its documentation doesn't list the features / benefits over plain yaml-mode.

>From reading the source, it looks like it provides
 * keyword highlighting (useful),
 * autocompletion of keywords (not useful), and
 * yasnippets templates (not useful).

It depends on packages named simply "s" and "f" (oy!), but
those appear to be in Debian already (elpa-s and elpa-f).
I installed those then did

    emacs -nw -q \
        -l emacs-ansible/ansible.el \
        -eval "(require 'yaml-mode)" \
        cyber-ansible/Cyber-BCP.yaml \
        -eval '(ansible +1)'

...and yeah OK, there's more color.  It treats "name: xxxx" specially,
and it tries to recognize the embedded jinja2 {{}} {%%} crap without
actually resorting to using an actual jinja major mode (via mumamo or
mmm).

I guess elpa-ansible would be useful to me, but
not enough to put you to any significant trouble.
I'll file an RFP and let you decide whether to action it. :-)
