Improve ispell.el word completion handling.
* ispell.el (ispell-alternate-dictionary): Use file-readable-p. Return nil if no word-list is found at default locations. (ispell-complete-word-dict): Default to nil. (ispell-command-loop): Use 'word-list' when using lookup-words. (lookup-words): Use ispell-complete-word-dict or ispell-alternate-dictionary. Check for word-list availability and handle errors if needed with better messages (Bug#6539). (ispell-complete-word): Use ispell-complete-word-dict or ispell-alternate-dictionary.
