This appears not to be mentioned in the style guide, but I think the convention
is to align the `.then` with the `fetch` above it.

That's how it is done in `subscriptionInit.js`. Given that it is a continuation
it is indented. The linter say so.

[Manish Jethani, 2018/06/13 16:53:09]

What I see in most places is this:

  func(
    param
  ).then(() => {})
   .then(() => {});

Since here func opens and closes on the same line, the `.then` would ideally be
aligned with the first character, like so:

  func(param)
  .then(() => {})
  .then(() => {});

When we break lines we continue the "expression" in the same column where it
started:

  let foo = 1 + 2 + 3
            4 + 5 + 6;
  let bar = one.two.three
            .four.five.six();

The linter doesn't care about this because we actually disabled some of these
rules for ESLint 4, if I remember correctly. But is the convention we are
following in general (so I hope).

Anyway, I can see some inconsistencies in this file, I don't care if it is all
fixed as a separate patch.

I just followed `lib/subscriptionInit.js:l202`

Other occurence `lib/io.js:109`

Acknowledged.
