The git blame manual page talks about using git blame --reverse to
figure out when a particular change disappeared, but I cannot make it
produce anything useful regardless of what range I give it.  Using
--root delivers a different state of uselessness.

Can anyone give a recipe for using git blame --reverse on the Git code
base for figuring out anything of relevance?

Since I am in the process of rewriting git-blame, of course I want to
verify that everything works, but while I achieve the same results, they
seem fabulously useless before and after my rewrite.

I rarely use blame, but the commit that introduces --reverse seems to
have an example. See 85af792 (git-blame --reverse - 2008-04-02)
