mysqldumpslow in 5.1.42 fails to parse slow log correctly

[Peiran Song]

Server version: 5.1.45-log Percona SQL Server (GPL), XtraDB 10.2, Revision 89

When run
  $mysqldumpslow <logfile>

Results are like:

Count: 1 Time=0.00s (0s) Lock=0.00s (0s) Rows=0.0 (0), dbm[dbm]@[10.10.101.211]
  # Thread_id: N Schema: pandora Last_errno: N Killed: N
  # Query_time: N.N Lock_time: N.N Rows_sent: N Rows_examined: N Rows_affected: N Rows_read: N
  # Bytes_sent: N Tmp_tables: N Tmp_disk_tables: N Tmp_table_sizes: N
  # InnoDB_trx_id: N
  # InnoDB_IO_r_ops: N InnoDB_IO_r_bytes: N InnoDB_IO_r_wait: N.N
  # InnoDB_rec_lock_wait: N.N InnoDB_queue_wait: N.N
  # InnoDB_pages_distinct: N
  SET timestamp=N;
  truncate table message_body2_20100802

A couple problems:
1) the stats line shows 0 for Time, Lock time, and Rows
2) numbers in header section were mistakenly abstracted out

Thanks for looking into it!
