Hello everybody,
I have sent this to the list about two month ago, but as the last patch was
neither committed nor commented I am resending.
This truncates menu title when it is longer than menu width. Otherwise no
title is displayed at all in this case.
This has been reworked to not touch the menu code but handle the truncation
within ui code instead.
