BUG#32205 Replaying statements from mysqlbinlog fails with a syntax error, replicates fine

The reason of this bug is that when mysqlbinlog dumps a query, the query is written to
output with a delimeter appended right after it, if the query string ends with a '--'
comment, then the delimeter would be considered as part of the comment, if there are any
statements after this query, then it will cause a syntax error.

Start a newline before appending delimiter after a query string
