It would help (me at least) if you could be more explicit about what 
exactly each instance is.

Apparently there is an 'original patch': is this the original patch by 
Marco Nenciarini?
Or is it something you posted earlier?

I guess it could be distilled from the earlier posts but when I looked 
those over yesterday evening I still didn't get it.

A link to the post where the 'original patch' is would be ideal...

thanks!
