I will explain this point in more detail if you don't mind. Here goes 
copy-pasted
1) the first the "lst" for hard disks and then
2)the second one the "sh" that makes the "lst" for partitions.
3) An "lst" for making easier to call the selection of partitions from 
inside a function or whatever.
4) An example of how this menues/selectors are called. (lst)

I'm not asking you to develop a command for giving me this lst on the 
fly adapted to the user pc. You know what I was telling before: If the 
users hard disk has only three partitions make an array with only three 
values which are the partitions.

I'm asking you to think about new features that scripting should have so 
that the developing of this command is far easy.

OFFTOPIC NOTE: I am working on grub legacy call and back commands so 
that what you see below actually works. I think this night it will work 
ok but who knows.
