As far as I can tell from half an hour of web searches, man page inspection, and
adding options like --quiet and --status-file /dev/null, there is *no* way to
suppress the message:

I wrote a CLI wrapper to grep encrypted files, and this info junks up its
output. It would be nice if I didn't have to see it.

Please correct me if there's a way to suppress this output and I just failed to
find it.

Thanks.
