    Description

      When using a template with an absolute Windows network path the opening of the QTemporaryFile fails because the path is not detected as an absolute path:

      QString absName = "\\\\localhost\\C$\\tmp.XXXXXX";
QTemporaryFile tmp(absName);
if (tmp.open())
{
   tmp.close();
}
else
{
   qDebug() << tmp.errorString();
}

      QFileSystemEntry::isRelative() does not consider UNC paths such that QFileSystemEngine::absoluteName() adds the current working directory to the already absolute path.
      Using '/' as file separator seems to work by mistake.
