When gluing two tokens, the second of which is joint, the result should also be joint. This fixes an issue with joining three `Dot` tokens to make a `DotDotDot` - the intermediate `DotDot` would not be joint and therefore we would not attempt to glue the last `Dot` token, yielding `.. .` instead of `...`.
