Fixed.  I've moved the Git final tag to the new version since finalization just happened.  (I'm aware that that isn't fully kosher Git practice.)

Shiro reported another error as well:

There seems a disagreement between srfi text and reference implementation.

The text says:

I'm beginning to understand that my own close reading before finalization is inadequate.  Thank you very much, Shiro, for your careful review.
