I am not sure if that would be workable.  I suspect that you
would need to do quite an involved sequence in "git branch" to
make this sequence to work with .git/deleted-refs/ scheme:

	git branch frotz/nitfol
        git pack-refs --prune
        git branch -d frotz/nitfol
        git branch frotz
        git pack-refs
        git branch -d frotz

After deleting frotz/nitfol you would create frotz/nitfol in
deleted hierarchy.  Then when you delete frotz you would need to
create frotz in deleted hierarchy, but you cannot, without
losing frotz/nitfol.
