+
+       Pessimize the code to simplify it: from now on, all the states
+       have a valid SHIFTS, which NSHIFTS is possibly 0.
+
+       * src/LR0.c (shifts_new): Be global and move to..
+       * src/state.c, src/state.h: here.
+       * src/conflicts, src/lalr.c, src/output.c, src/print.c,
+       * src/print_graph: Adjust.
+

+
+       * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
+       * src/conflicts.c: Use it.
+       Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
+       incorrectly ``simplified''.
+
+

        * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
