From: Johannes Schindelin <johannes.schindelin@xxxxxx> In 6956f858f6 (notes: implement helpers needed for note copying during rewrite, 2010-03-12), we introduced a test case that verifies that the config setting `notes.rewriteRef` can be overridden via the environment variable `GIT_NOTES_REWRITE_REF`. Back when it was introduced, it relied on a side effect of an earlier test case that configured `core.noteRef` to point to `refs/notes/other`. In 908a320363 (t3301: modernize style, 2014-11-12), this side effect was removed. The test case *still* passed, but for the wrong reason: we no longer overrode the rewrite ref, but there simply was nothing to rewrite anymore, as the overridden notes ref was "modernized" away. Let's let that test case pass for the correct reason again. To make sure of that, let's change the idea of the original test case: it configured `notes.rewriteRef` to point to the actual notes ref, forced that to be ignored and then verified that the notes were *not* rewritten. By turning that idea upside down (configure the `notes.rewriteRef` to another notes ref, override it via the environment variable to force the notes to be copied, and then verify that the notes *were* rewritten), we make it much harder for that test case to pass for the wrong reason.
