[GNC] Issue posting vendor bill with non-US dollar book

[Paul Kroitor]

I guess the question is "should a machine in <Country A> doing the books 
of a business operating in <Currency B> create new vendors in A or B?"

If A is France and B is Vietnam, then probably the answer is A. But if A 
is Australia and B is Bitcoin, then the answer seems (at least) less clear.

I'm not sure about my own view on the above is, but I do still maintain 
that fundamentally if you tell your machine it's in Canada, this entire 
class of problems would be greatly mitigated. Glad you're will to look 
at it. It's trivial to change -- and reverse, if you don't like the 
results -- but it may change other apps you didn't realize were doing 
things based on locale.
