[PATCH] t4013: add expected failure for "log --patch --no-patch"

From: Sergey Organov <sorganov@gmail.com>
Date: May 3, 2023, 13:41 UTC
Message-ID: <20230503134118.73504-1-sorganov@gmail.com>

--patch followed by --no-patch is to be a no-op according to the "git log" manual page. In reality this sequence breaks --raw output though (and who knows what else?)

Add a test_expected_failure case for the issue.
