docs: Transform parsed structure into pluralization n.b. The first node may
  be a non-integer (for instance, a string representing an Arabic
  number). So convert it back with the current language's
  convertNumber.
  
  @param {Array} nodes List [ {String|Number}, {String}, {String} ... ]
  @return {String} selected pluralized form according to current
  language.
