[syslinux] Final line of menu selectable even if it is disabled

[Matt Sephton]

I have a menu conf as follows:

LABEL enabled, use as item
LABEL disabled, use as description
SEPARATOR
LABEL enabled, use as item
LABEL disabled, use as description

In this situation, I expect the cursors to be able to select from only the two enabled lines. 

However, the final disabled line is also selectable. 

Even if I put a final separator and/or disabled label the final line of the menu is still selectable. 

Full conf: http://pastebin.com/U6zQVbt6

So there seems to be an edge case scenario that means the final line of a menu is selectable when it should not be. 

Any thoughts?
