      Documentation says that if a dir exists, then `QDir::mkpath(path)` should return `true`. This however does not work for drives.

      #include <QDebug>
#include <QDir>

 int main()
{
    qDebug() << QDir().mkpath("C:/Windows"); // returns true
    qDebug() << QDir().mkpath("C:/"); // returns false
}

      This hurts applicability. I cannot write `QDir().mkpath(parentDir);` to ensure that `parentDir` either exists or is created, unless I check beforehand whether the `parentDir` is a drive or a plain dir.
