mytop-1.9.1-queries-vs-questions-mysql-5.0.76.patch

In MySQL 5.0.72 the Questions variable was changed to only contain the number
of client-initiated queries, NOT the number of overall queries. This caused
problems with the select/insert/update/delete percentages because Com_* was
still based on the overall queries.

MySQL 5.0.76 introduced a new variable 'Queries' with the behavior of the old
Questions variable.
