Subject: [PATCH v2 01/13] t6120-describe: correct test repo history graph in comment

From: SZEDER Gábor <[email-masked]>
Date: Tue, 12 Nov 2019 11:38:09 +0100

At the top of 't6120-describe.sh' an ASCII graph illustrates the
repository's history used in this test script.  This graph is a bit
misleading, because it swapped the second merge commit's first and
second parents.

When describing/naming a commit it does make a difference which parent
is the first and which is the second/Nth, so update this graph to
accurately represent that second merge.

While at it, move this history graph from the 'test_description'
variable to a regular comment.
