[PATCH v2 1/4] t4015: modernise style

From
Junio C Hamano <gitster@pobox.com>
Date
May 26, 2015, 19:46 UTC
Message-ID
<1432669584-342-2-git-send-email-gitster@pobox.com>
In-Reply-To
<1432669584-342-1-git-send-email-gitster@pobox.com>

Move the preparatory steps that create the expected output inside the test bodies, remove unnecessary blank lines before and after the test bodies, and drop SP between redirection operator and its target.
