How can I unstash and clobber or only copy if changed?

[red 888]

Im running into a java.nio.file.AccessDeniedException error when trying to unstash to a folder with the same files/folders.

Ideally I'd like unstash to overwrite files only if changed, but if unstash would just clobber every file/folder conflict that works too.

I'd be nice to avoid rm * -rf here
