Line formatting issues

[wdoug]

Currently, this transform does not maintain whitespace. This is something that appears to not be supported with the TypeScript printer that is used for this transform, so this might be complicated to resolve. Maybe there is an option to try to add back whitespace after the main transformation. Alternatively, if we could use something like jscodeshift for this transform we wouldn't have this issue, but that seems likely to be a lot of work.
