I think this patch should be split in two or three: First a
non-functional preparatory patch that does all the renaming and moves
sprinter creation up and passes it as parameter. Second the functional
patch(es) that add sexp support to reply and show.

Please find some other comments below.

Ditto.

Please add braces to all branches if you add them to some.
