That didn't seem to help. I tried overriding selectedRanges, and that makes you
delete the whole range when you are clicked in it (good), but nothing seems to
help the case of trying to simply backspace from the end of the range. In this
case the selected range is not relevant because you are not inside the range
yet as far as the existing range, and you can't predict in advance the user
intends to backspace into it, and for the same reason, neither is the
rangeForUserTextChange.

I don't think you really want to override that method. Instead override
-[NSTextView selectionRangeForProposedRange:granularity:] which should be
called for every selection the user makes.
