Should this `break` changed to `continue`?

If registries from current yaml_file is none, it should continue to next yaml_file. Current atomic trust show doesn't show sigstore from all of the yaml files under /etc/containers/registries.d

[qiwan@qiwan registries.d]$ ls -a
.  ..  default.yaml  docker.io-qiwanredhat.yaml
[qiwan@qiwan registries.d]$ cat docker.io-qiwanredhat.yaml 
docker:
  docker.io/qiwanredhat:
    sigstore: file:///var/lib/atomic/sigstore/

Should file:///var/lib/atomic/sigstore/ shows at the end of 3rd line?

$ atomic trust show
* (default)                         accept                               
docker.io                           accept                               
docker.io/qiwanredhat               accept                               
quay.io/crio/hello-world            reject                               
registry.access.redhat.com          signed security@redhat.com,security@redhat.com

Yes I think so.
