    dfa: fix off-by-one under-allocation from recent change
    Commit v2.19-10-gc32ff67 mistakenly made this change:
      -realloc_trans_if_necessary (d, 1);
      +realloc_trans_if_necessary (d, 0);
    which led to a heap buffer overflow.
    * src/dfa.c (dfaexec): Allocate space for one state, as before.
