QTableView::keypressEvent() with [move] keys and count() > 1 calls moveCursor() only once

In Mixxx we have a QTableView with a custom keypressEvent() that directs "move keys"¹ to a function² for shifting item rows up/down.

keypressEvent() receives actual and emulated keypresses, the latter can have count() > 1.

Regardless the QKeyEvent::count(), moveCursor() is called only once.

If the same code is built with Qt5, moveCursor() is called N times as desired.

¹Up, Down, PageUp, PageDown, Home, End
