Which didn't make it easier to read. Can't you take out such patches before 
you make new ones?

Anyway: There once was code in kfile that did the sorting a bit different than
what it's now. It sorted the chunk (e.g. the 150 items) and then used a 
merging algorithm to get the new chunk in the whole list instead of sorting 
the new list from scratch. But I guess you only notice the difference if you 
have 7000 instead of the 1200 items. For the 1200 items (and problably quite
some other cases), your patch helps anyway, so I think you should commit
(the listing part :)
