Oh, this wasn't the case when I started my checks. There was a rewrite of
the contents generator one or two years ago, I guess that the change
happenend at that occassion.

I'll have a look. If the contents files are sorted lexicographically by
the name of the file then it should be easy to merge input from several
files. There will, however, be a certain loss in performance since at
the moment I use a regexp to simply skip over files that occur only in
one package, and that is no longer possible when we several input streams.

-Ralf.
