Fair enough.  However, I'm leaning to adding string-replace! and string-append!
to Kawa, since the functionality is useful and easy to implement.  If you or
anyone has any comments on the names and parameters of those functions it
would be welcome, especially if any other Scheme implementations or libraries
have something similar.

When it comes to BuffersCowan, it seems reasonable enough.  One comment:
What is the point of point?  I.e. the concept seems redundant if you have
markers. In Emacs point is a special marker corresponding to the "current
position", but I don't think that makes sense for a Scheme library API.
(Even in Emacs, the concept of a buffer-point is dubious.  A window-point
makes sense, of course.)
