[syslinux] 3 Bugs in SysLinux -3.86

[Ilya Zakharevich]

As the first step, I want to thank everybody involved for making a
majorly useful application!

Second, here are the problems I see:

Bug 1: if DEFAULT is not a tag, but a kernel name, menu.c32 fails loading.

Bug 2: When menu.c32 returns to syslinux (on pressing Esc), the splash
       screen is not shown;

Bug 3 or a missing feature:

        When grub.exe tries to return control to syslinux, it fails.
	This happens when the user choses (in the standard menu.lst of
	grub4dos distribution) the entry:

		title back to dos
		quit

	  Most probably the problem 3 would be very hard to work
	  around - how would syslinux know where to reload itself
	  from?  It might have been loaded by some chainloader...

Thanks again,
Ilya
