[PATCH 4/5] t4108: demonstrate bug in apply

From
Denton Liu <liu.denton@gmail.com>
Date
Oct 23, 2019, 12:03 UTC
Message-ID
<5feddf15978e77b19d8b3e2e5761e394e0bda3e7.1571832177.git.liu.denton@gmail.com>
In-Reply-To
<cover.1571832176.git.liu.denton@gmail.com>

Currently, apply does not respect the merge.conflictStyle setting. Demonstrate this by making the 'apply with --3way' test case generic and extending it to show that the configuration of merge.conflictStyle = diff3 causes a breakage.

Change print_sanitized_diff() to also sanitize `|||||||` conflict markers.
