If you use plain "HEAD" (a commit-ish) instead if HEAD^{tree}, then
git archive will store the commit id in the archive metadata and the
user can then use git get-tar-commit-id to extract it.

... then this HEAD file might not even be necessary (even if you keep
it, it would be nice not to break git get-tar-commit-id).
