So I want it that if you try and delete any character that is part
of a token, it deletes the entire token.
So I'm overriding rangeForUserTextChange to return a different
range if the current range includes any part of a token.
This seems to work if the user tries to type in any part. For
example, clicking on the token and pressing space bar or a letter.
However, it doesn't work if you press backspace or delete, even
though rangeForUserTextChange is still called.
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.
