+    The line number area is now painted every time the cursor blinks
+    (because we connect \l{QPlainTextEdit::}{updateRequest()} to
+    \c updateLineNumberArea()). We can avoid this by introducing a new
+    member variable to CodeEditor that keeps track of when the update
+    request comes from a cursor blink (in which case we do not
+    repaint). The code below requires the \c m_countCache variable,
+    which is a QPair<int, int> initialized with \c -1 for both
+    \l{QPair::}{first} and \l{QPair::}{second}.
