elsif タグの複雑な条件分岐のフォーマッティング

It should not break singular expressions, but we break children
printWidth: 1
{% if false %}
{% elsif x %}
  hello
{% endif %}
{% if false %}
{% elsif 'string' %}
  hello
{% endif %}
{% if false %}
{% elsif null %}
  hello
{% endif %}

It should break before logical operators
printWidth: 1
{% if false %}
{% elsif conditionA
  and var.key
  and true
%}
  hello
{% endif %}

It should break before comparators (and indent)
printWidth: 1
{% if false %}
{% elsif lower
    < some.variable
  and some.variable
    < upper
%}
  hello
{% endif %}

It should try to keep comparators on same line
printWidth: 30
{% if false %}
{% elsif lower < some.variable
  and some.variable < upper
%}
  hello
{% endif %}

It should support all kinds of shit
printWidth: 30
{% if false %}
{% elsif lower < some.variable
  and some.variable < upper
  and string contains 'hi'
  or string == empty
  or null
  or var.lookup
%}
  hello
{% endif %}

It should support all kinds of shit (same but for unless)
printWidth: 30
{% unless false %}
{% elsif lower < some.variable
  and some.variable < upper
  and string contains 'hi'
  or string == empty
  or null
  or var.lookup
%}
  hello
{% endunless %}
