Sorry, I meant just

  (substitute-command-keys "(\\<icomplete-fido-mode-map>\\[icomplete-fido-exit] 
to end): ")
  => "(M-j to end): "

not necessarily called in the minibuffer, but with the minibuffer's keymap.

A more complex solution like proposed by João would be to set a certain
property set on a command's symbol that exits the minibuffer.

But maybe 'cond' in Andrew's path with an additional substitute-command-keys
(for the case when the user remaps the default keys) is fine.
