Desired Behaviour

ansible-lint should allow for Jinja whitespace control, e.g. {{- and -}}.

The reason for using yaml multiline string here is, that I need to build a string without newlines from multiple variables with defaults from other variables which leads to the line being longer than 160 chars.

Actual Behaviour (Bug report only)

---
- hosts: localhost
  vars:
    fooo: asadsafdsafdsafdsafadsfdsa
    bar: 15.6
    baz: x86_64

  tasks:
    - debug:
        msg: |
          {{ fooo }}/
          {{- bar }}/
          {{- baz }}

ansible-lint /tmp/abc.yml
[206] Variables should have spaces before and after: {{ var_name }}
/tmp/abc.yml:12
          {{- bar }}/

[206] Variables should have spaces before and after: {{ var_name }}
/tmp/abc.yml:13
          {{- baz }}

[ssbarnea]

I confirm that I enounter this bug in an alternative way: {{ var_name -}} as dash suffix is also part of the jinja2 specification and AFAIK there is no workaround.
