yeah, i knew that, but specifying the complete name of the menu option
for grub-set-default is tedious and error prone.

actually, this bug annoys me less now that i've modified by
grub-list-kernels.pl script to deal with submenus, so i can use the "1>0"
style numbering easily.

e.g.

# grub-list-kernels.pl
   0	Debian GNU/Linux	
   1	Advanced options for Debian GNU/Linux	
 1>0	Debian GNU/Linux, with Linux 3.8-1-amd64	
 1>1	Debian GNU/Linux, with Linux 3.8-1-amd64 (recovery mode)	
 1>2	Debian GNU/Linux, with Linux 3.7-trunk-amd64	
 1>3	Debian GNU/Linux, with Linux 3.7-trunk-amd64 (recovery mode)	
 1>4	Debian GNU/Linux, with Linux 3.2.0-4-amd64	
 1>5	Debian GNU/Linux, with Linux 3.2.0-4-amd64 (recovery mode)	
   2	Network boot (iPXE)	
   3	Bootable floppy: LSI	
   4	Bootable floppy: freedos-bare	

  Default: 0  "Debian GNU/Linux"

I'll attach a copy of the script to this message - feel free to add it
to the package if you like.

OK, I'll do that. need to create a login on savannah first.

FYI, the patch I sent is not quite complete - also need to
add GRUB_ENABLE_SUBMENUS to the list of exported vars in
/usr/sbin/grub-mkconfig.


i probably should submit my grub-list-kernels.pl script as a contrib
item there, too.
