From ceec1361ebbc4613813ba42976503f5e304cfacf Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Mon, 17 Jul 2006 15:06:23 -0700 Subject: [PATCH] pack-objects: reuse deflated data from new-style loose objects. When packing an object without deltifying, if the data is stored in a loose object that is encoded with a new style header, copy it without inflating and deflating.
