+It seems we have never tested the case that restore --accumulate\r
+actually adds tags. I noticed this when I started optimizing and no\r
+tests failed.\r
+\r
+The bracketing with "restore --input=dump.expected" are to make sure\r
+we start in a known state, and we leave the database in a known state\r
+for the next test.\r
