It is called when you turn on minor mode `icicle-mode'.

As I said, there are about 30 such "other functions", and all of their
definitions are different.  But I guess you are interested in the context of the
definition and not the definition itself.

All are defined pretty much at the top level of an Icicles file, so they get
defined each time the file is loaded.  (The defalias for the `old-*' function to
restore to is done only on the first load of the file.)  E.g.:

(unless (fboundp 'old-display-completion-list)
  (defalias 'old-display-completion-list
            (symbol-function 'display-completion-list)))

(defun icicle-display-completion-list (completions &optional ignored)
  ...)

In this example, `icicle-display-completion-list' would be the file that Emacs
thinks is defined in `tramp-compat.el'.
