Interesting that this is dead code.  Looks like that happened independent of the
formatter.

Brian: any idea what the story is?

The earliest commit of this file is
https://code.google.com/p/dart/source/detail?r=23769, which you committed,
labeled "Dart formatter babysteps.". It seems reasonable that this file wasn't
referenced outside the formatter. (You can see the whole history here:
