    graftcopies: document why the function is useful at all · 06e7e7652ac0

    Despite having spent a significant amount on time on the copy-tracing
    code, I thought `graftcopies()` (formerly known as
    `duplicatecopies()`) was needed to duplicate copies after calling
    `merge.update()` to do a merge (as `merge.graft()` does), but it's
    actually usually not needed; `merge.update()` takes care of most
    copies. This patch documents what the function is for.
