Look at the larger picture.
In this function, the desired result isn't some kind of exact value which
is valid for each and every situation. We don't really need micro-level
correctness here. We're just trying to come up with an algorithm which
gives us diplomat production in just about the right number of cities, and
preferably in cities close to the action.
The previous code meant that cities if different players close to each
other produced too many diplomats overall. The fix changes this slightly
to the better (giving a better supply curve to use a term from economics).
Of course, if you can come up with a(n even) better algorithm here, all
the better. After all, you're the math wizard ;)
