Actually the LCD code will work fine with LCDs with two or more lines so
your first assumption is incorrect. All the code does assume there are
at least two lines available though and will require a lot of change to
make it work with one line displays.

The off by one patch you supplied is incorrect. The top line (topWidget)
shows the menu name and then any other lines available (menuWidgetX)
show the menu items so the code as it stands is correct.
