Range information is inconsistent for Program nodes with leading whitespace

// espree 3.4.3

require('espree').parse('/* foo */ bar /* baz */', { range: true })

Output

{
  "type": "Program",
  "start": 0,
  "end": 23,
  "range": [
    10,
    13
  ],
  "body": [
    {
      "type": "ExpressionStatement",
      "start": 10,
      "end": 13,
      "range": [
        10,
        13
      ],
      "expression": {
        "type": "Identifier",
        "start": 10,
        "end": 13,
        "range": [
          10,
          13
        ],
        "name": "bar"
      }
    }
  ],
  "sourceType": "script"
}

The Program node has start: 0 and end: 23, but its range is [10, 13].

This happens because espree transforms the range property to match Esprima’s behavior. The transformation is correct, but we should also update the start and end properties, since they’re equivalent in all other cases.

I am working on this. This should probably be a breaking change.
