Subject: [PATCH 20/21] show-index: acknowledge that it does not read .idx v3

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Wed, 11 Sep 2013 13:06:21 +0700

show-index takes .idx from stdin while v3 requires the .pack. It's
used for testing purposes only. Let those test scripts force .idx v2
with index-pack.
