Comment Handling

I tried to work on comments in #20 (closed), and think I made some progress, but I've either broken other things, or found new test cases that I don't yet test for.

publish => [
  # external:internal
  "${ext_port}:443", #lint:ignore:array_formatting
],

gets incorrectly formatted to

publish => [
  # external:internal        "${ext_port}:443", #lint:ignore:array_formatting      ],

Now, the array close is part of the comment, and messes all kinds of stuff up.

I've got a few examples of this now, and it looks like my plugin shoves all the lines together until it finds a comma.
