`git tag --points-at` can simply return if the given rev does not have

I disagree. I think the 0 return means "I completed successfully" and 
the empty output means "I didn't find any tags pointing to this object."

Changing the return value here could break a lot of scripts out in the 
wild, and I consider this to be an "API" compatibility that needs to 
stay as-is.

What are you using "--points-at" where you need a nonzero exit code 
instead of a different indicator?

Thanks,
