Removed FULL option from SHOW BINARY LOGS

Browse Source 
If option ‘binlog_structure’ is set to ‘tree’ then SHOW BINARY LOGS
displays the tree details of the binlog files.

MySQL [(none)]> SHOW BINARY LOGS;
+--------------------------+-----------+
| Log_name                 | File_size |
+--------------------------+-----------+
| 0/10122/mysql-bin.000117 |      1167 |
| 0/10122/mysql-bin.000118 |       652 |
| 0/10124/foo-bin.000016   |      5082 |
| 0/10124/foo-bin.000017   |       491 |
+--------------------------+-----------+

With option set to ‘flat’ (which is the default) the output contains
only
names:
