This code has been working nicely so far. I'll keep using it to see if it has any unexpected side effects.

No, this only affects things going on in the slime-repl buffer.

On second thought, it might not be too hard to change that behavior.
(Might need to think the implications through though.) Can you try

(No need to restart SLIME or anything, just M-x eval-region that.)
