C++ (Cpp) KateView::up示例

// This is a unit test for bug 311866 (http://bugs.kde.org/show_bug.cgi?id=311866)
// It loads 5 lines of C++ code, places the cursor in line 4, and then folds
// the code.
// Expected behavior: the cursor should be moved so it stays visible
// Buggy behavior: the cursor is hidden, and moving the hidden cursor crashes kate
