Thanks.
I see that someone has cleaned up the code. That's suitable, but a 
detail has rendered the change useless :(

The line
         INCLUDED=$INCLUDED'\n'$MOD
should be
         INCLUDED=$INCLUDED$'\n'$MOD
or else the grep -qFx won't succeed.

(Fortunately, I couldn't help noticing the mistake, because the sorting 
procedure ran as slow as it used to :)
