Jason Gustafson reopened KAFKA-5327:
------------------------------------

I have reverted this change in KAFKA-5414 since it breaks existing usage. It seems like a simpler option is just to ensure that max.poll.records is not set higher than max messages.

> The ConsoleConsumer has a --max-messages flag that can be used to limit the number of messages consumed. However, the number of records actually consumed is governed by max.poll.records. This means you see one message on the console, but your offset has moved forward a default of 500, which is kind of counterintuitive. It would be good to only commit offsets for messages we have printed to the console.
