We now at least import other pack settings like pack.window, which means we can later use these to control how we search for deltas. The compression level was fixed to use pack.compression rather than the loose object core.compression setting. Change-Id: I72ff6d481c936153ceb6a9e485fa731faf075a9a Signed-off-by: Shawn O.
