+       Fix some comments concerning LR(0) versus LALR(1).
+
+       Stop equating LR(0) with nondeterminism and LALR(1) with
+       determinism.  That is, if all states are consistent, then LR(0)
+       tables are deterministic.  On the other hand, LALR(1) tables
+       might be nondeterministic before conflict resolution, and GLR
+       permits LALR(1) tables to remain nondeterministic.
+       * src/LR0.c, src/LR0.h: Here.
+       * src/lalr.c, src/lalr.h: Here.
+       * src/main.c (main): Here.
+       * src/state.c, src/state.h: Here.
+
+       * src/ielr.h (ielr): In preconditions, expect LR(0) not LALR(1)
+       parser tables.
