Empty ruleset throws exception

[jonnor]

#parameterSection {

}

When #parameterSection selector matches

Throws RangeError: Invalid array length at args = Array(length); inside Command.prototype.descend
Inspection shows length is -1

Need to look into this but FYI we already have a test for this:

parse """
          article.featured > img {

          }
          """
        ,
          {
            commands: [
              ['rule',
                ["tag",[">",['.',['tag','article'],'featured']],"img"]
                []
              ]
            ]
          }

Should we then lower the restriction in the error inspector?

These are probably handled differently since the spec relies on plural bindings vs the original example which uses an ID.
