To address Sergey's concerns, testing on my end _seems_ to indicate that it does inherit the whitespace option. Since this is not a serious breaking change, I'm going to integrate it. If it turns out to break editor formatting for someone somewhere, we can easily back this out later

Oops, before I integrate, this should have the ide-support flag too
