When a typewriter mode is active, changing the document string scrolls to bottom

[DivineDominion]

It's not unusual for a NSTextView to place the insertion point (selectedRange) at the end of the document when you set its string to a new value. Usually, it doesn't scroll down there, though. Depending on the use case, this might not be desirable.

I figure this is due to the fixInsertionPointPosition() call which is there to do just that: re-set the selectedRange to make the view scroll and/or forceLayoutWithNewInsets().
