Documentation:
Icomplete-specific customization of minibuffer setup.

This hook is run during minibuffer setup if Icomplete is active.
It is intended for use in customizing Icomplete for interoperation
with other features and packages. For instance:

(add-hook 'icomplete-minibuffer-setup-hook
(lambda () (setq-local max-mini-window-height 3)))

will constrain Emacs to a maximum minibuffer height of 3 lines when
icompletion is occurring.

You can customize this variable.
