Re: [PATCH v5 8/8] fetch-pack: implement ref-in-want

+test_expect_success 'setup repos for change-while-negotiating test' '

The tests that follow are basic ref-in-want tests, not tests on a repo
that changes during negotiation - this would be just "setup repos for
fetch tests".

+test_expect_success 'fetching with exact OID' '
+	rm -rf local &&
+	cp -r "$LOCAL_PRISTINE" local &&
+	git -C local fetch origin $(git -C "$REPO" rev-parse d):refs/heads/actual &&
+
+	git -C "$REPO" rev-parse "d" >expected &&
+	git -C local rev-parse refs/heads/actual >actual &&
+	test_cmp expected actual
+'

Also verify that "want-ref refs/tags/d" is being sent over the wire, and
not any "want ...". (If not we can't distinguish these from the usual
non-want-ref behavior.) Same comment for the other tests.

Other than that (and my other comments), this patch series looks good.
