* Some tools use @@hostname without /*!50038*/
* pt-deadlock-logger error: Use of uninitialized value $ts in
pattern match (m//)
* pt-heartbeat --utc --check always returns 0
* pt-heartbeat docs don't account for --utc
* pt-query-digest 2.1 typo in docs
* pt-query-digest docs don't mention --type=rawlog
* pt-table-checksum doesn't use non-unique index with highest
cardinality
