[syslinux] Menu system exit

[Murali Krishnan Ganapathy]

I think I know what is happenning. Whenever OPT_EXITMENU is selected, 
the value of curr will be set to NULL. That explains the behaviour.
One way around is to replace the last add_item with

add_item("Exit this menu","Go back...",OPT_RUN,"mainmenu.com",0);

and then you dont need the "if curr->action == OPT_EXIT" line. While 
this should work (I dont think PXELinux has anything to do with it),
the only difference you will see is the absence of (<< when the item is 
being displayed).

If I come up with a cleaner solution, I will let you know.
