Specifying the argument ($ tsc --removeComments) or option in (tsconfig.json) for removing comments is not honoured.

Normal comments are removed, but special comments, like references and amd dependencies, are preserved.

/// <reference path="../Interfaces/IView" />
/// <reference path="./BaseView" />
/// <amd-dependency path="/js/libs/hgn.js!app/templates/home" name="compiler"/>

I don't know if this new behaviour is intended but this wasn't the case in the previous release and I wouldn't expect these special comments to be required in the output files.
