What about the case when s1 and s2 are nil? Shouldn't there be another
(t (< (length c1) (length c2))) at the end of the second cond ? Am I
missing something?
It seems cleaner to sort two times, instead of once with both
predicates, the way it's already done in the code for recently used
completions.
Also, the comment needs changing.
What about this?
