Public bug reported:

We are required to withhold the VAT payment of the supplier and pay it
directly to the government.  So, I have defined a Withholding tax (equal
to VAT but negative) that gets booked to a Payable type account.

In the Pay Invoice wizard (launched from the Supplier Invoice) when I
make a full payment and click the "Fuil Payment" button it brings up a
form for writing off the difference between the payment amount and what
it thinks is the correct amount.  If instead I click on the "Partial
Payment" button everything functions correctly and the transaction is
posted to the financial accounts correctly.

After some debugging I found that the problem is that when it calculates
the full payment it includes lines matching the account on the invoice
*and* also any amounts booked to payable or receivable  accounts.
Apparently this behaviour is due to a fix committed for bug #496889.  I
have attached a patch that additionally filters by whether the move line
is a tax.

I am using OpenERP 5.0.14.
