Um. Ok. That tells us that the font designer was slightly inefficient. 
That's not going to cause any rendering problems.

PfaEdit does check whether curves can be replaced by lines. Its check is 
mathematically precise.

It is also an irrelevant fix.

I have looked at the copies of Nimbus Sans I have on my machine and there 
is no curve in B where there should be a line. In the examples you gave all 
I see are a bunch of hlineto operators.
