Deindent comments following hanging assignment

[jbodah]

Below we see that the comments do not correctly deindent after the assignment

 defmodule MyApp do
   import Supervisor.Spec
   use Application

   @cluster_id 123
   @registry MyApp.Registry
   @thing MyApp.Thing
   @thing MyApp.Thing
   @thing MyApp.Thing
   @thing MyApp.Thing
   @thing MyApp.Thing
   @thing MyApp.Thing

   # See http://elixir-lang.org/docs/stable/elixir/Application.html
   # for more information on OTP Applications
   def start(_type, _args) do
     MyApp.thing([])

     # Define workers and child supervisors to be supervised
     children = [
       worker(MyApp.Thing, []),
       worker(MyApp.Thing, []),
       worker(MyApp.Thing, []),
       worker(MyApp.Thing, []),
       worker(MyApp.Thing, []),
       worker(MyApp.Thing, []),
       worker(MyApp.Thing, []),
       worker(MyApp.Thing, []),
       worker(MyApp.Thing, []),
       worker(MyApp.Thing, []),
       worker(MyApp.Thing, []),
       worker(MyApp.Thing, []),
       worker(MyApp.Thing, []),
       worker(MyApp.Thing, []),
     ]

     children =
       if System.get_env("THING") == "1" do
         children ++ [
           supervisor(Thing, [])
         ]
       else
         children
       end

-   # See http://elixir-lang.org/docs/stable/elixir/Supervisor.html
-   # for other strategies and supported options
-   opts = [strategy: :rest_for_one, name: MyApp.Supervisor]
-   Supervisor.start_link(children, opts)
+      # See http://elixir-lang.org/docs/stable/elixir/Supervisor.html
+      # for other strategies and supported options
+    opts = [strategy: :rest_for_one, name: MyApp.Supervisor]
+    Supervisor.start_link(children, opts)
   end
 end

More specifically:

     children =
       if System.get_env("THING") == "1" do
         children ++ [
           supervisor(Thing, [])
         ]
       else
         children
       end

       # See http://elixir-lang.org/docs/stable/elixir/Supervisor.html
       # for other strategies and supported options

should be:

     children =
       if System.get_env("THING") == "1" do
         children ++ [
           supervisor(Thing, [])
         ]
       else
         children
       end

     # See http://elixir-lang.org/docs/stable/elixir/Supervisor.html
     # for other strategies and supported options
