[PATCH v3 2/4] test-lib.sh: introduce and use $_EMPTY_BLOB

From
Nguyễn Thái Ngọc Duy <pclouds@gmail.com>
Date
Jul 9, 2016, 05:23 UTC
Message-ID
<20160709052356.30570-3-pclouds@gmail.com>
In-Reply-To
<20160709052356.30570-1-pclouds@gmail.com>

Similar to $_EMPTY_TREE this makes it easier to recognize this special SHA-1 and change hash later.
