+position relative to other test names. This requires that the failure list is
+already sorted. This does not guarantee that the tests will appear neatly one
+after the other, as there may be comments in between. If the failure list
+is not sorted, sorted blocks may be produced, but the list as a whole will not.
+Lastly, be wary of lists that have tests stripped from OSS; if you catch that
+a test was added inside a stripped block, you may need to move it out.

 This is sort of like comm(1), except it recognizes comments and ignores them.
