Problems around removing all todo items

[PeterPerhac]

I've gone and removed all todo items from the list, which left me with a blank item number 1. After adding a new item, which was meant to be the only item on my todo list, it was assigned number 2, just below a blank todo item.

==> v
1. foo
2. bar
3. baz

rm 1
rm 1
rm 1
add hello
v

expected output

1. hello

actual output

1.
2. hello

I understand the app is not about TODO list management :-) (but i'd still expect it to work) I came here mainly for the GraalVM parts and that is very interesting. I have the same motivation to make my personal Scala command line utilities start up faster and this looks wonderful - so BIG THANKS for taking the time to create this repo and write up the article!
