Re: String Builder insert

Well, that works for this specific example of course. But by simply
resetting sb.Length after inserting you are truncating as many characters as
you just inserted from the end of the StringBuilder instance. That's fine if
we're just dealing with spaces (as in this example), but it might not be
what you want in all cases.
