+       (new_states): Merge into...
+       (generate_states): here.
+       (set_states): Don't ensure a proper `errs' state member here, do it...
+       * src/conflicts.c (conflicts_solve): here.
+       * src/state.h, src/state.c: Comment changes.
+       (state_t): Rename member `shifts' as `transitions'.
+       Adjust all dependencies.
+       (errs_new): For consistency, also take the values as argument.
+       (errs_dup): Remove.
+       (state_errs_set): New.
+       (state_reductions_set, state_transitions_set): Assert that no
+       previous value was assigned.
+       (state_free): New.
+       (states_free): Use it.
+       * src/conflicts.c (resolve_sr_conflict): Don't use an `errs_t' as
+       temporary storage: use `errs' and `nerrs' as elsewhere.
+       (set_conflicts): Allocate and free this `errs'.
