Hm, why is this recorded as a delete and creation? Weird, inspecting the
diff locally properly shows it as a rename, which makes it a ton easier
to review. It would be great if you could try to play around with the
`--find-renames` option in the next iteration of this series and double
check that these are shown as a rename.

This doesn't got to do anything with indices but with refs, so I'd
rename this to `__ref_read_write()`.

+	cl_assert(ret == 0);
Same comment here, asserts like this can be retained as
`cl_assert(!ret)`.

+	rec.u.ref.value_type = REFTABLE_REF_DELETION;
+	ret = block_writer_add(&bw, &rec);

+
+	for (i = 0; i < N; i++) {
+		rec.u.ref.refname = xstrfmt("branch%02"PRIuMAX, (uintmax_t)i);
+		rec.u.ref.value_type = REFTABLE_REF_VAL1;
+		memset(rec.u.ref.value.val1, i, REFTABLE_HASH_SIZE_SHA1);
+
+		recs[i] = rec;
+		ret = block_writer_add(&bw, &rec);
+		rec.u.ref.refname = NULL;
+		rec.u.ref.value_type = REFTABLE_REF_DELETION;

It's a bit unfortunate that we have to use `cl_assert()` here, but that
isn't the fault of this series. I do have a pull request pending
upstream that introduces integer comparisons. Once we've updated to that
version I'll go through our unit tests and adapt callsites accordingly.

+void test_reftable_block__ref_read_write(void)
This one here should be called `__index_read_write()`. I guess you
confused the first and and this test name with one another.
