Underlying assumptions in the business features that Invoices are always
on sign and Payments are always the other. A negative payment would
therefore look like an Invoice.. but it's NOT an invoice.. And it would
confuse the payment-merging processing for handling over/under-payments
across multiple invoices.
Feel free to look at src/business/business-core/gncInvoice.c if you want
to try to come up with a better approach.
