{A.a, b} is reformatted incorrectly

[cknitt]

The following code

module A = {
  type t = {a: int, b: string}
}

let f = (~a, ~b) => {A.a, b}

gets reformatted to

module A = {
  type t = {a: int, b: string}
}

let f = (~a, ~b) => {A.a: A.a, b: b}

which does not compile.

Instead, it should be reformatted to

module A = {
  type t = {a: int, b: string}
}

let f = (~a, ~b) => {A.a: a, b: b}

Or even better, the punning in the original code should be kept as is, see also rescript-lang/syntax#47.
