Didn't we just have this discussion?
It is extremely hard for pre-extending strings to result in actual
performance improvements, and at best you can get a very small win in
return for a lot of work. In fact the extra effort of having to track
where you are in the string manually almost certainly *loses*
performance.
So don't do it.
