Remove comma_first_indentation_workaround

Remove the workaround implemented to allow a vertical alignment of
objects' properties. That feature could be considered too complex and
also an unwanted behaviour by some.

The changes proposed in this commit make objects look like this:

    myObject = {
      prop1: 1
      , prop2: 2
      , prop3: 3
    };

Without these changes objects would look like this:

    myObject = {
      prop1: 1
    , prop2: 2
    , prop3: 3
    }
