+
+       * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
+       only when appropriate: when insert_start_shifting_state' is not
+       invoked.
+       * tests/regression.at (Rule Line Numbers): Adjust.

+
+       * src/LR0.c (augment_automaton): Now that all states have shifts,
+       merge the two cases addition shifts to the initial state.

+       * src/lalr.c (set_state_table): Move to...
+       * src/LR0.c: here.
+       * src/lalr.c (lalr): Don't call it...
+       * src/LR0.c (generate_states): do it.
+       * src/LR0.h (first_state): Remove, only the table is used.

+
+       * src/LR0.h (first_shift, first_reduction): Remove.
+       * src/lalr.c: Don't use first_shift: find shifts through the
+       states.

+
+       * src/LR0.c: Attach shifts to states as soon as they are
+       computed.
+       * src/lalr.c (set_state_table): Instead of assigning shifts to
+       state, just assert that the mapping was properly done.

+       * src/LR0.c (insert_start_shift): Rename as...
+       (insert_start_shifting_state): this.
+       (insert_eof_shifting_state, insert_accepting_state): New.
+       (augment_automaton): Adjust.
+       Better locality of the variables.
+       When looking if the start_symbol is shifted from the initial
+       state, using `while (... symbol != start_symbol ...)' sounds
+       better than `while (... symbol < start_symbol ...)': If fail
+       to see how the order between symbols could be relevant!
