options doesn't accept input in the same format that it outputs

{{{
04/19:46:31 options.getgeneral
04/19:46:34 Options: pluginname.optionname=value
04/19:46:42 options.setgeneral pluginname.optionname=newvalue
04/19:46:43 Syntax: '!options.setgeneral ='.
}}}

It should accept the "pluginname.optionname=newvalue" syntax, ideally supporting multiple options set at once.
