I once dealt with code that looked like this pattern (sorry for the giant vertical size of this post):

  DO_F() {
    A;
    B;
    C;
    D;
    B;
    C;
    D;
    E;
    F;
    A;
    B;
    C;
    D;
    G;
    H;
    I;
    J;
    A;
    B;
    C;
    H;
    I;
    // a bunch more
  }

So I suggested, "hey perhaps you should break this into functions" and got back:

  DO_F() {
    A;
    B;
    C;
    D;
    B;
    C;
    D;
    E;
    F;
    A;
    state.a = a;
    state.b = b;
    // ... for other state
    return DO_F2(state)
  }
  DO_F2(state);
    B;
    C;
    D;
    G;
    H;
    I;
    state.a = a;
    //...
    return DO_F3(state);
  }
  DO_F3();
    J;
    A;
    B;
    C;
    G;
    H;
    I;
    // a bunch more
  }

When I suggested blocks such as B; C; D; or G; H; I; could be functions, and perhaps a loop could be useful too, the guy looked at me like I was trying to do voodoo and got really defensive about how that couldn't possibly work.

I think that is what the OP meant by bulldozer code...
