[PATCH v4 4/9] t3701: don't hard code sha1 hash values

From
PWPhillip Wood <phillip.wood@talktalk.net>

<20180301105103.24268-1-phillip.wood@talktalk.net>
From: Phillip Wood <phillip.wood@dunelm.org.uk>

Use a filter when comparing diffs to fix the value of non-zero hashes in diff index lines so we're not hard coding sha1 hash values in the expected output. This makes it easier to change the expected output if a test is edited as we don't need to worry about the exact hash value and means the tests will work when the hash algorithm is transitioned away from sha1.

Thanks-to: Junio C Hamano <gitster@pobox.com>

Notes:
    changes since v3:
     - fix zero hash values to seven digits
    changes since v2:
     - fix hash values in index lines rather than removing the line
     - reworded commit message
