[GNC] Duplicate invoice numbers

[Macho Philipovich]

Dear Gnucash users,

I've ended up with about five pairs of invoices where each pair both 
share the same invoice number, due to bug #799118

My question is, short of simply unposting one of each pair, recreating 
them with a new/proper invoice number, and just abandoning the unposted 
ones like that, is there any thing I can do to recover from this?

Presently I don't believe I can even print them all because in reports 
you select the invoice only by invoice number.

Many thanks,

Macho
