Yeah, I think it's better to keep it as a warning. It's actually
reasonably likely to be benign (e.g., you did a "git repack -ad && rm
/path/to/alternate" to remove the dependency, but forgot to clean up the
alternates). And when it _is_ a problem, the object-reading code paths
will definitely let you know.
