I see. What if you go back to your original attempt and set MAX_LINES to 11? Will it then "stop" at 10?

For instance, let's say I hit my limit, but I hit it like this: a a a a a a a aaaaaaaaaaaa I should be able to go up in the first couple lines and keep typing, because it won't push the bottom line out any further...
