Recast strips leading whitespace based on the first line of a template literal in a function

[nickretallack]

Input:

/* @flow */
() =>
  `
  x
`

Output is the same regardless of the --no-prettier setting:

() => `
x
`;

It also fails verification:

verification failed, diff after stripping type annotations:
- Expected
+ Received

  () => `
-   x
+ x
  `;

If you pass --no-recast it leaves the code unchanged.

Here's a similar example that it leaves unchanged:

/* @flow */
() => `
  x
`

It converts this example into the example above:

/* @flow */
() => 
`
  x
`

If you input this:

/* @flow */
() =>
  `
    x
`

It gives you this:

() => `
  x
`;

Very interesting! It seems like it's trying to do something nice for you, by looking at the first line of the template and stripping that amount of whitespace from the following lines. In another context, that'd be pretty cool. But here, I just want it to leave my code alone.
