1743 Note: this function is "ugly" because it is called for every menu
1744 item once, while the popup widget in turn scans through the menu
1745 items - but there is no other way to correct the problem with having
1746 at the same time an accelerator key (string after \t (tab)) and a
1747 submenu arrow displayed!
1748
1749 btw., the Windows style solves that problem by always having some space left
1750 for the arrow, and Motiv overpaints the arrow over the accelerator string,
1751 but native PM handles the case in a flexible and correct way!...
