Docs or code for log_slow_verbosity = standard are wrong

[Daniel Nichter]

PS 5.1, 5.5, and 5.6 docs say "standard: Equivalent to enabling microtime,innodb" but this is not true:

Server version: 5.6.13-rc61.0 Percona Server (GPL), Release 61.0

mysql> SET global log_slow_verbosity=standard;

mysql> select @@global.log_slow_verbosity;
+-----------------------------+
| @@global.log_slow_verbosity |
+-----------------------------+
| microtime,query_plan |
+-----------------------------+

And the actual slow log output agrees that only microtime,query_plan are set:

# Time: 150813 16:58:24
# User@Host: root[root] @ localhost [] Id: 272
# Schema: fipar Last_errno: 0 Killed: 0
# Query_time: 0.000377 Lock_time: 0.000096 Rows_sent: 3 Rows_examined: 3 Rows_affected: 0
# Bytes_sent: 959 Tmp_tables: 0 Tmp_disk_tables: 0 Tmp_table_sizes: 0
# QC_Hit: No Full_scan: No Full_join: No Tmp_table: No Tmp_table_on_disk: No
# Filesort: No Filesort_on_disk: No Merge_passes: 0

So either docs are wrong, or the code is not properly aliasing/setting standard=microtime,innodb.

Easy to confirm with 5.6.
