I severely doubt that most loops through process-environment will be prepared to encounter a non-string argument (doing string-match on all encountered elements would be sort of a natural operation). An empty string, in contrast, would probably not do much harm, I suppose. If there are many such loops, and changing them would be hard, this might be an important factor. Otherwise, we should do the cleanest thing, and use nil, and change those loops.
