If you run "config --blob" outside of a repository, then we eventually try to resolve the blob name and hit a BUG(). Let's catch this earlier and provide a useful message. Note that we could also catch this much lower in the stack, in git_config_from_blob_ref(). That might cover other callsites, too, but it's unclear whether those ones would actually be bugs or not. So let's leave the low-level functions to assume the caller knows what it's doing (and BUG() if it turns out it doesn't).
