I know this is inconsistent. But in the first versions of the cache, it
was even worse: *all* parent folders got the overlay, even unversioned
folders and the drive icon ;)
Now we at least check first if the parent is versioned before we
propagate the child status upwards. But that's all we do. And I think
that's all we *can* do without adding a huge check/validation routine to
the cache, which of course will slow it down remarkably.
