We have already scanned the same reflog in the backward direction in full. Do we need to make another call just to pick up the entry at the beginning? Is this because the callback is not told that it is fed the last entry (in other words, if there is some clue that this is the last call from for-each-reflog-ent-reverse to the callback, the callback could record the value it received in its cb-data)? -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
