Historically, it was a mistake to allow A..B to be used for two
endpoints, which was made back when we haven't thought things
through.  That is why I stopped "warn to deprecate and then
completely remove", as I do not think it would help people very much
if "git diff A B" can be spelled with two-dots.

But in a distant future long after that happens, by the time nobody
remembers what A..B meant for "git diff", I do not think I'd
strongly be opposed to reusing it to mean something different.
