Prettier Liquid: Simple behaviour (positional args + named args)

[charlespwd]

A couple of tags support positional and named arguments. We should format those properly.

Input

{% section     'foo'  %}
{% increment   bar   %}
{% cycle a, b[a], c.a-thing["a"] %}

Expected

{% section "foo" %}
{% increment bar %}
{% cycle a, b[a], c["a-thing"].a %}

Closing as this seems simple but there are edge cases. E.g. layout takes none as a special argument.
