Which is why I'd strongly consider having it only in the repository
object as that is the largest-scoped thing we'd want. e.g. submodules
should care about environment variables differently:

    GIT_WORK_TREE=~/mysuperproject git checkout \
            --recurse-submodules master

 So with such a command in mind, the environment variable would
only apply to the superproject and the nested submodules should
ignore the env, but compute their paths off the superproject, i.e.
the superproject repository, not its object store?
