formatter cause syntax error. about crystal HOT 2 OPEN

This looks like two bug: The formatter should not butcher full-line comments in an argument list. But the parser should also be able to read the resulting code. There's nothing wrong with it.

So keeping this issue focussed on the formatter, I created #14616 for the parser bug.

Can be reduced:

Before

foo do
      bar(
        arg1: "",
        # arg2: ""
      ) do
      end
    end

After

foo do
  bar(
    arg1: "" # arg2: ""
,
  ) do
  end
end
