[syslinux] Comboot menu crashes when it goes off screen

[Aaron McSorley]

Resetting the position at a certain menu level would do the trick. I like the
look and feel of the menu except for the part when the sub menus hit the
right side of the screen and wrap around to the left. I would like it to stop
or bounce back when it hits the edge of the screen. This could be simulated by
setting the menu position to 0,0 at about level 4.

Could you give an example on how to set menulevel. I dont get any result when
I set it to a number like 2 or 3. 

If I do something like:
 
unsigned int menupos_handler(unsigned int par_tl, unsigned int menu_width,
                             int child_index, int menulevel)
{
  return menulevel + 0x0313;
}

I get the main menu in the corner and all submenus show up at row 3 column 13.
That's kind of neat but, I dont think thats how it's supposed to work.
