Value filter in Path can omit closing square bracket character

[braveulysses]

A Path with a value filter is considered valid if it omits the closing ] character, though such a Path should be considered invalid. This is something that @dvernon-uid noticed some time ago.

Example:

{  
   "colors": [  
      "red",
      "green",
      "blue"
   ]
}

The path colors[value eq \"blue\"] is valid, as expected, but so is colors[value eq \"blue\".
