(switch-to-completions) when completion-show-help is nil fails

Debugger entered--Lisp error: (search-failed "

  search-forward("\n\n")
  (progn (select-window window) (goto-char (point-min)) (search-forward "\n\n")

Since the "\n\n" is part of the help text.  The one line change to
simple.el works around the problem:
