Cool - thank you very much.  I tried it shortly, and it works for me.

One thing I found: at the end of `string-edit', you have

#+begin_src emacs-lisp
(message "%S" (substitute-command-keys
                 "Type `C-c C-c' when you've finished editing"))
#+end_src

That should be "%s" - we don't want a quoted, `read'able string
messaged.

Second: I find the name of `read-string-from-buffer' a bit misleading -
what about `edit-string-in-buffer'?  The emphasis should be on "edit",
because a string is already present, the function doesn't just prompt
for a (new) string.

Thanks,

Michael.
