globals under overrides does not work for me

[guy-mograbi-at-gigaspaces]

this is my configuration

"xo" : {
    "space" : 4,

    "overrides" : {
      "test" : "test/*.spec.js",
      "globals" : [ "it" , "describe" ]
    }

  }

and I am getting

test/test.spec.js
  8:1  error  "describe" is not defined  no-undef
  9:5  error  "it" is not defined        no-undef

The overrides feature is not released yet. The readme reflects current master. The release is blocked by #71.
