Wrapper for extra indent function for val-node.

@param {Array} nodes all nodes
@param {Number} i position in nodes array
function extraIndentVal(nodes, i) {
    var subset = [];
    var declaration = nodes.get(i);
    if (!declaration.is('declaration')) return;

    for (var x = declaration.length; x--;) {
      if (!declaration.get(x).is('value')) continue;

      x--;

      while (!declaration.get(x).is('propertyDelimiter')) {
        subset.push(declaration.get(x));
        x--;
      }

      break;
    }
    return extraIndent(subset);
