- Fixed problem, only detect comment if the # is on start of line AND starting line of the current command.
- Wrote tests for most of the mysqltest commands, added stricter checking of correct syntax.
and fixing it another way (per Monty; a simpler solution which does not increase the number
of binlog events is to always execute DROP TEMPORARY TABLE IF EXISTS on slave). A new test rpl_drop_temp.
2) fixing BUG#8436 "Multiple "stacked" SQL statements cause replication to stop" by setting
thd->query_length to the length of the query being executed, not counting the next queries
if this is a multi-query. Should also improve display of SHOW PROCESSLIST. A new test rpl_multi_query.
