Thank you to Mr. Shiro Kawai, who provided a patch for SRFI
113.  (See below.)  John Cowan, author of SRFI 113, has
approved, so I've pushed this to the Git repository and to
the web site.  Note that this involved changes only to the
reference implementation, not to the SRFI document.

Thanks!

SRFI Editor
