setting enable_query_response_time_stats in my.cnf is not error prone

[Kenny Gryp]

When you want to set 'enable_query_response_time_stats' you need to use:

[mysqld]
enable_query_response_time_stats=1

It does not work when you set it to:
enable_query_response_time_stats=ON
Or when you set it to:
enable_query_response_time_stats

This is not a behavior I would expect.
The documentation also mentions:
Type Boolean
Default Value OFF
Range ON/OFF

- Note that percona server also does not give any warning or fail to start. It silently ignores the setting and leaves it off-
- tested under version 5.1.57 - 12.8

Also, the documentation for 5.1 is incorrect. http://www.percona.com/doc/percona-server/5.1/diagnostics/response_time_distribution.html

It is still enable_query_response_time_stats in latest PS 5.1

Current 5.5 query_response_time_stats is a bool variable, thus it should work correctly. Please re-open if it's not the case.
