I agree that empty lines should not be added into the history, but I 
don't think it is a good idea to show an empty line when you go down 
the history. Because I really like to have compatibility with BASH.

I don't know how the current implementation behaves very well, but it 
should work in the same way as GRUB legacy. It should be like this:

PROMPT        HISTORY
grub>         []
foo[RET]
grub>         ["foo"]
bar[RET]
grub>         ["foo", "bar"]
[RET]
grub>         ["foo", "bar"]
[C-p]
grub> bar     ["foo", "bar"]
[C-n]
grub>         ["foo", "bar"]
[C-p]
grub> bar     ["foo", "bar"]
baz[RET]
grub>         ["foo", "bar", "barbaz"]
