Bug #79828 mysqldumpslow does not aggregate times

Description:
Hi Team,

mysqldumpslow does not aggregate times/rows (query_time/lock_time; rows_sent/rows_examined) in MySQL 5.7.10 version.

Best Regards,

Ivan Pavlovic

How to repeat:
The slow quey log is activated and contains entries like:

The aggregated times/rows from mysqldumpslow output are always 0.00 (N.N), so sort by query_time/lock_time/rows_sent is not possible:
