Purpose
=======
On a payslip rule computation you can return 3 parameters:
- result_qty
- result_rate
- result
From this, we compute the total amount as following:
tot_rule = amount * qty * rate / 100.0
If we set parameters result_qty=0 or result_rate=0 to force the tot_rule to
be equal to 0, then their values are set to the default one, which is ambiguous.
So
result_qty = 0
result_rate = 0
Become
qty=1
amount=100
We can't fix this in a stable release as this could imply unwanted
behavior changes for customers, and also quite difficult to spot.
