Hi,

I was looking at the isn extention to store EAN13 value.  A lot of those
that I want to store are about books so they are also an ISBN13.

My problem now is that I it's always displayed with the dashes in between,
even when I want to show the EAN13.  As far as I know EANs are never shown
with the dashes.

For EANs that aren't books it's also doing XXX-XXXXXXXXX-X, which I also
don't want.  For UPC it seems to do what I want.

I think the output should depend on wheter I want to show an ISBN or EAN.
