+       (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'.

+       (states_free): Use it.
+       * src/conflicts.c (resolve_sr_conflict): Don't use an `errs_t' as

+       (set_conflicts): Allocate and free this `errs'.
