So, any last changes to SRFI-105?

I found a minor inconsistency in the list of Unicode characters in the precedence discussion.  The whole section is *NOT* a required part of SRFI-105, so it can't affect implementations directly, but I thought I may as well fix it.  Here it is, attached.

Unless I hear something in a few hours, this is the final version of SRFI-105.
