Can you extract out just the changes necessary to deal with the fine_life_end

This is *PRECISELY* why this code is so messed up -- you've got way too many
interdependencies between your patches.  And I will NOT approve a mega-patch.
We do not allow other folks to submit huge mega-patches, we require them to
break them into manageable hunks.  You will need to do the same or we'll have
to pull the recombine_givs and related code out _again_.
