 * Fixed a bug whereby Menhir would warn about a useless `%prec` declaration,

 * Modified the meaning of `--canonical` to allow default reductions to take
   place. This implies no loss of precision in terms of lookahead sets,
   and should allow gaining more contextual information when a syntax
   error is encountered. (It should also lead to a smaller automaton.)
