Not interested. When the user gets that "fatal" message, the existing tag did not get modified, so they can just do whatever check they want (like "git range-diff v1.9.5...hello") themselves. Besides, in the above examples, is d4e6038a something the user immediately recognises as the same as v1.9.5 or the object existing v1.9.5 tag points at? I somehow doubt it. So after getting the error, there needs some digging to figure out how v1.9.5 and existing hello are related to each other _anyway_, I would think.
