There are no completions shown initially because after adapting
icomplete-mode I removed the hook 'post-command-hook'
that is the workhorse of icomplete-mode and that is
called initially to handle no input, and replaced it
with the hook 'after-change-functions' because only
changes on the minibuffer should affect the shown
completions.  So an additional call of zcomplete-exhibit
should be added to the end of zcomplete-minibuffer-setup.

Maybe these fixes should be applied to a new branch.
