'innodb = FORCE' configuration not document and seams ineffective

Hi,

I ran into a configuration that included:
"innodb = FORCE"

I could not find this in the documentation anywhere, looked into the documentation of MySQL 5.0 and upwards.

I removed the configuration and compared SHOW GLOBAL VARIABLES output. There were no changes. Apparently this configuration does nothing.

I think a deprecation message should be place, or the server should not start with it as it's a incorrect variable. Or, if it does have a function, that should be documented.

Cheers,
Michael
