These tokens don't current add any value, but actually produces a bug where a SyntaxError due to mis-applied ++ operator mentions "--" instead of "++".

I'm gonna investigate why there are EWS failures.
I was wrong about AUTOPLUSPLUS not being needed. It’s needed to distinquish this:
statement ++ stuff
AUTOPLUSPLUS tells us that that there’s a `\n` there, which tells us that the ++ is a prefix for the next token, not a postfix for the last one.
So, the real bug is that the SyntaxError message needs to take into account AUTOPLUSPLUS.

Thanks for the review. The AS Mac failures are not related.
