Yes, however doing that fully correctly seems a bit tricky, I thought 
that pointing to the id_loc it's still better than a rather meaningless 
place near the end of the line, eg, before the semicolon. Note this is a 
more general issue, I'll give it some thought... I'm leaving those 
friends alone for the time being.

Thanks, Paolo.
