First off, wow - that's a lot of changes - and as far as I can tell all good.   Thanks for getting rid of the pre-begin cursor and adding useful things like string-join, and string-contains.

Just a few things I noticed in the early part of the document.  It will take me a while to get through the rest of it.

In the Procedure Index, string-cursor-prev is misspelled "string-cursor-end" -- the link target
seems to be correct.

The links in the Procedure Index section for string-cursor<? through string-cursor>=? seem to be
broken.  Same for string-cursor->index and string-index->cursor.

In the Procedure Index, string-contains has no link.

In the Rationale section, you refer to "eql?" in the context of comparing an arbitrary object to a char.   I assume you meant eqv?

In the section on Shared Storage, you suggest substring/cursors is both allowed and not allowed to return shared storage.

    I've just published a new draft of SRFI 130 from John
    Cowan. I've included his notes below.
