The break at this line is not inconsistent with the `return QModelIndex()` at line 776 (line 764 in the new patch) because that line is inside another for loop. It is indeed not consistent with the old code at line 750 (line 738 in the new patch) which I didn't noticed before. I've changed this in the new patch to be consistent with the old style.
