MariaDB CLI client doesnt show CREATE INDEX progress

MariaDB supports progress informations about queries such as ALTER TABLE or CREATE INDEX that can be followed on the PROCESSLIST.

The problem is that on the CLI client, while the progress of operations such as an ALTER TABLE is shown while the command is running, nothing is shown at all for a CREATE INDEX operation.

–
Example of what is show on the CLI while running an ALTER TABLE operation :

MariaDB [database]> ALTER TABLE sometable ADD COLUMN newcolumn char(4) DEFAULT NULL AFTER othercolumn;

Stage: 1 of 2 'copy to tmp table'  0.007% of stage done

Similar progress infos should be printed while running a CREATE INDEX operation but nothing is shown.
