Subject: Make icomplete-exhibit actually work when navigating up directories

Make icomplete-exhibit actually work when navigating up directories

Sometimes, when finding files with icomplete-mode, backward-deleting
the previous word or sexp (to move up a directory) doesn't actually
refresh the file list of the new directory.  Forcing redisplay in
icomplete-exhibit misteriously fixes the problem.

* lisp/icomplete.el (icomplete-exhibit): Add call to redisplay.
