Maybe just creating a new element might be more efficient. Or maybe this is just negligible.

Maybe just creating a new element might be more efficient. Or maybe this is just negligible. This only happens each time we encounter a new number of sequential spaces. In my experience, I haven't seen more than 32 in a row before. I don't think this is something we need to worry about.
