This started out to as a hunt for remaining qsort() calls after rs/qsort
series because qsort() API is a bit easy to get wrong (*). However,
since we have string_list_sort(), it's conceptually a better way to sort
here.
(*) In this particular case, it's even more confusing when you sort one
variable but you use the number of items and item size from an unrelated
variable (from a first glance)
