broken syntax coloring in Ruby on list used as default parameter

[matkoniecz]

Issue Type: Bug

module CartoCSSHelper
  def self.test_tag_on_real_data(tags, new_branch, old_branch, zlevels, types = ['node', 'closed_way', 'way'], min = 4, skip = 0)
    types.each do |type|
      test_tag_on_real_data_for_this_type(tags, new_branch, old_branch, zlevels, type, min, skip)
    end
  end
end

It is a valid syntax that will confuse code highlighting
