ok, i just commited this with the following changes:

1) we don't attempt to add a slime-repl-result-face property if
   there's no result in slime-repl-insert-prompt.

2) renamed *current-id* to the (imho) more emacs-ish
   slime-current-output-id and added a defvar so repl shortucts don't
   break.

3) inserting a previous output now moves point past the inserted text
   (previously the pint was being left in the middle of the text).

4) inserted output is still undeleteable :( i tried messing with the
   intagible and modification-hooks properties but don't have enough
   emacs-foo to figure this out.

5) attempting (via M-p or similar) to access an output which has been
   cleared (via C-c C-t or similar) signals a error with a message
   explaining what's happened.
