The current 0.2.0rc0 S3 --buckets option doens't work as expected:

go run main.go -C ~/.aws/credentials s3 bucket --buckets foo
OK - 1 Buckets: 0 Critical - 0 Warning - 1 Ok
 \_[OK] mopolka-delete-me - value: 100MiB | mopolka-delete-me=100MB;10240;20480

go run main.go -C ~/.aws/credentials s3 bucket --buckets foo --buckets bar
OK - 2 Buckets: 0 Critical - 0 Warning - 2 Ok
 \_[OK] mopolka-delete-me - value: 100MiB
 \_[OK] mopolka-delete-me - value: 100MiB | mopolka-delete-me=100MB;10240;20480 mopolka-delete-me=100MB;10240;20480

I think the culrpit is the internal/s3/client.go those functions needs some refactoring
