Well, looking at these two very different fixes, it made me think that
you don't really know what you're doing. So I went and did the Knuth's
version just so that I can analyze and understand the issue myself.

The final result ended up needing *both* the index fix *and* removed the
trailing noodling code after the loop which looked fishy at best and I
wanted it gone anyway.

So in the end:

1. your first fix was correct but incomplete

2. your second was replaced by a better version of the whole thing

So the final result is a lot cleaner and straight-forward. And it is
only 29 lines and I don't see a problem with it going to stable.

And I as author and maintainer of this code have very much the
prerogative to decide which way to go, TYVM. No matter how much you
passive-aggressively bitch. Thanks to your last mail, I won't have to
make this choice anymore.
