Thanks.  `company-strings' is indeed fast.  Unfortunately the return
value is odd.  It returns a positiv/negative number if different, but t
(instead of 0) when they are equal.  That means some work to turn it
into a compatible predicate...

(byte-compile
 (lambda (a b)
   (let ((v (compare-strings a nil nil b nil nil t)))
     (or (eq v t) (< v 0)))))

All this fuss eventually makes it slower... :(

Nikolaj Schumacher
