model.toJSON and collection.toJSON unused options argument

[drinchev]

This is not an issue at all, but while I was reading backbone.js I found out that there is unused options argument for those two methods :

// in Backbone.model

    toJSON: function(options) {
      return _.clone(this.attributes);
    },

// in Backbone.collection

    toJSON: function(options) {
      return this.map(function(model){ return model.toJSON(options); });
    },

is this intentional ?

It's handy if you want to write your own toJSON method. see #1098

I thought the purpose might be this... Although I checked the issues page for "toJSON", I probably missed #1098's commits. Thanks
