Iterating strings with for

[jg-rp]

When looping over strings with the {% for %} tag, the reference implementation of Liquid will iterate over a one element array, where the first and only element is the string. Python Liquid will iterate through characters in the string.

Template:

{% assign foo = 'hello world' %}
{% for x in foo %}{{ x }} / {% endfor %}

Ruby Liquid Output:

hello world /

Python Liquid Output:

h / e / l / l / o /   / w / o / r / l / d / 

It appears that this is unintended behaviour for Ruby Liquid. Previously, Ruby Liquid would iterate over lines in a string, also not intended behaviour. See Shopify/liquid#1667.
