I don't think you need the first occurence of the word "will" here -
documentation should always read as if this is the way things are now,
it's the way things have always been, and the way they always will be in
the future (except the "Since x.y.z" tags).
Aside from this, I'm still uncomfortable about the lack of new tests
here, because my own experience is that new code is alsmot always
incorrect until it's been run through some tests. But since you're
remedying this problem in a later patch in the series, I'm okay with it.
