Subject: [PATCH v2 2/4] t4015: separate common setup and per-test expectation

From: Junio C Hamano <[email-masked]>
Date: Tue, 26 May 2015 12:46:22 -0700

The last two tests in the script were to

 - set up color.diff.* slots
 - set up an expectation for a single test
 - run that test and check the result

but split in a wrong way.  It did the first two in the first test
and the third one in the second test.  The latter two belong to each
other.  This matters when you plan to add more of these tests that
share the common coloring.

While at it, make sure we use a color different from old, which is
also red.
