BTW, there is another TODO item in minibuffer.el:
;; - indicate how to display the completions in *Completions* (turn
;; \n into something else, add special boundaries between
;; completions). E.g. when completing from the kill-ring.
Such pre-processing can be performed by the caller.
For a long time I used the command 'yank-from-kill-ring'
bound to 'C-M-y' that relies on query-replace-descr
to display newlines as ^J and displays long completions
with an ellipsis at the end and an ellipsis on leading whitespace.
These pre-processed completions also needed to display
shorter strings in the minibuffer in icomplete-mode,
so this is usable in icomplete-mode as well:
