Yep, you have it correct. I've got a note at the bottom of the README that I'm considering adding a config field to keep the .git directory, but I'm trying to keep pretty far away from git-in-git consequences/use cases. I said the same in another comment here, but I don't envision vdm becoming something that's git-specific or developmental -- it's really just intended to be a getter, not a writer, and the functionality reflects that.

Cool info though, thanks for sharing!
