pt-table-checksum - issue in info message for MyRocks

The message looks like:

# pt-table-checksum h=127.0.0.1,P=20795,u=msandbox,p=msandbox
Checking if all tables can be checksummed ...

The RocksDB storage engine is not supported with pt-table-checksum since RocksDB does not support binlog_format=STATEMENT.
We have identified the following tables using MyRocks storage engine:
test.t1

Please add ROCKSDB to the list of --ignored-engines
--ignored-engines=FEDERATED,MRG_MyISAM,RocksDB

Conversely exclude the MyRocks tables explicitly:
--ignore-tables=test.t1

Aborting%

1. It says

--ignored-engines=FEDERATED,MRG_MyISAM,RocksDB

but it seems that the option is really

--ignore-engines

- just a small typo but I used copy-paste and noticed it.
Also notice this is mentioned in the line above that one also.

2. Last line is "Aborting%" which possibly wouldn't be confusing without "%" but with that it looks unfinished and in your example in PT-204 I see something like "Aborting at bin/pt-table-checksum line 10126." so most probably it's some issue.

My environment was ubuntu xenial - used deb packages - not tarball (maybe important for #2).
