      Description

      Some strange behavior around $all. Unclear to me what is right, but it does seem that 2.5 should not be matching this document. The way I see it is that "a" does not contain the object [""], it IS that object, thus this should not be matched.

      In 2.5:

      > db.repro.insert({_id: 0, a: [""]})
      > db.repro.find({a: {$all: [[""]]}})
      { "_id" : 0, "a" : [  "" ] }
      > db.runCommand({buildinfo: 1})
      {
              "version" : "2.5.5-pre-",
              "gitVersion" : "f65a0b814b8c77e3fbe90bca0c061c9b77f6acdb",
