At some point in the past, the MySQL command line client was modified to remove \r before \n in its input.
This caused problems in some workloads, specifically when loading BLOB fields containing \r characters. Percona Server solves this by implementing a new command line client option, no-remove-eol-carret.
When the no-remove-eol-carret option is specified, \r before \n is not removed.
