r = Repo.clone_from("git@github.com:bpiotr/whatever_repo.git", "/tmp/repo", env={"key": "value"})r.git.environment(){}

This is not what I expected when I calledRepo.clone_from and documentation does not elaborate on the transient nature of theenv here so IMHO this is a bug.

BTW it costed me quite a while to figure out thatclone_from actually usesenv but any subsequent operations on the result needs it to have it set again.
