What I meant by "Consider it done" was that I will update the rules to
further clarify what is a token and what is not. And try to keep it
simple. I'm obviously failing miserably to do this.

Not quite. A token character can be letters, digits, hyphen, or a quote.
The list of valid token characters has been unchanged since day one. The
problem seems to be that certain combinations of these token characters
are not real tokens. These are the *exceptions* to the rule. I wanted to
put in some exceptions so that you'd have to really think about your
approach, and it gives various different opportunitites for optimization.

Read the rules again. I am *not* saying that at all.
