-Also: there's a nasty hack here called "showtest" which, when run like
-``./showtest 07/03'', will show you the ways in which my output

+Appendix: queries that should fail
+----------------------------------
+
+The following queries are included in Rob's master list, in a final
+section called "Invalid searches [should error]". They are all
+expected to fail in various ways. I've taken them out of
+"queries.raw" because it's uninteresting, not to mention rather
+disturbing, to watch compilers fail. More important, I think, to
+demonstrate correct behaviour for the known-to-work queries.
