Improve formatting of a sequence of identifiers

[shaobo-he-aws]

Describe the improvement you'd like to request

The formatter currently does a horrible job in formatting a sequence of identifiers. For instance,

// An example from RFC
permit(
  principal is User,
  action == Action::"preview",
  resource == Movie::"Blockbuster"
) when {
    // extended has
  principal has 
  // contactInfo
  contactInfo.
  // address
  address.
  // zip
  zip &&
  // we are safe to access all attributes
  principal.contactInfo.address.zip == "90210"
};

is formatted into,

// An example from RFC
permit (
  principal is User,
  action == Action::"preview",
  resource == Movie::"Blockbuster"
)
when
{
  // extended has
  principal
  has
    // contactInfo
    contactInfo.
      // address
      address
      .
      // zip
      zip &&
  // we are safe to access all attributes
  principal.contactInfo
    .address
    .zip == "90210"
};
