The itch is legit, but I doubt a "special log for deleted branches" is a
good design.  Why do you limit yourself only to a single "last" commit?
Wouldn't it be a better design to save away the entire reflog for the
branch when a branch is deleted, possibly with expedited expire rule for
such a reflog?
