Code formatter losing multilines in maps

[pragdave]

This may be related to the previous one, but:

defp package do
    [
      files: [
        "lib", "mix.exs", "README.md"
      ],
      maintainers: [
        "Dave Thomas <dave@pragdave.me>"
      ],
      licenses: [
        "Apache 2 (see the file LICENSE.md for details)"
      ],
      links: %{
        "GitHub" => "https://github.com/pragdave/mix_templates",
      },
      version: @version,
    ]
  end

is formatted as

  defp package do
    [
      files: [
        "lib",
        "mix.exs",
        "README.md"
      ],
      maintainers: [
        "Dave Thomas <dave@pragdave.me>"
      ],
      licenses: [
        "Apache 2 (see the file LICENSE.md for details)"
      ],
      links: %{"GitHub" => "https://github.com/pragdave/mix_templates"},
      version: @version
    ]
  end

I really like the way it split files: onto multiple lines. But is also rewrapped links: onto one line.
And, in the process, it removed the spaces after %{ and before }.

Cheers

Dave

This is the same bug as #6646.
