I was using the default template for an invoice this
week, and I found that the line and Thank You were
missing. Thinking back to earlier times, this was a
problem I had before.
My solution at the time was to move it up, but I also
put in a remittance section (Cut here ----- Remit with
payment) just like on utility bills.
I'll submit a patch to the default template in English,
but I don't know where to go from there. I haven't
checked any further templates for correctness.
The patch adds some space below the rule line.
