yq -n errors out with tty input

[pisto]

A discrepancy with jq:

[pisto@kp ~]$ jq -rn '"ok"'
ok
[pisto@kp ~]$ yq -rn '"ok"' < /dev/null 
ok
[pisto@kp ~]$ echo | yq -rn '"ok"'
ok
[pisto@kp ~]$ yq -rn '"ok"'
usage: yq [options] <jq filter> [YAML file...]
[...]

Thanks for pointing this out. This should be fixed in 36995e5; released in v2.12.2.
