+
+       Stop storing rules from 1 to nrules + 1.
+
+       * src/LR0.c, src/closure.c, src/derives.c, src/gram.c, src/lalr.c
+       * src/nullable.c, src/output.c, src/print.c, src/reader.c
+       * src/reduce.c: Allocate and free from &rules[0], not &rules[1].
+       Iterate from 0 to nrules.
+       Use rule_number_as_item_number and item_number_as_rule_number.
+       Adjust to `derive' now containing possibly 0.
+       * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
+       Handle the `- 1' part in rule numbers from/to item numbers.
+       * src/conflicts.c (log_resolution): Fix the message which reversed
+       shift and reduce.
+       * src/output.c (action_row): Initialize default_rule to -1.
+       (token_actions): Adjust.
+       * tests/sets.at (Nullable, Firsts): Fix the previously bogus
+       expected output.
+       * tests/conflicts.at (Resolved SR Conflicts): Likewise.
