playback doesn't handle multi-line queries in slow log

[Gavin Towey]

If you send a query to mysql with newlines in the query string, mysql will write the query across multiple lines. However, playback seems to assume that each line is a full query:

Take this sample slow log:
/usr/sbin/mysqld, Version: 5.5.13-55-log (Percona Server (GPL), Release rel20.4, Revision 138). started with:
Tcp port: 3306 Unix socket: /dbname/mysql/app/mysql.sock

SELECT
 column
FROM
 table
WHERE foo=1

Running that file through the program generates these errors:
