Nested @ArgGroup adds @Options on outer level of command #722
Description
In the example code below I have created a command that has nested @ArgGroup options but there appears to be an issue where the options in the inner most arg group (i.e. --level-3a-param <level3aParam> and --level-3b-param <level3bParam>) are also being reported as available options in the outer level.
Usage: arg-group-test create (--level-1-param <level1Param> (--level-2a-param
<level2aParam>) (--level-2b-param <level2bParam>
(--level-3a-param <level3aParam>)
(--level-3b-param <level3bParam>)))
--level-0-param <level0Param> --level-3a-param
<level3aParam> --level-3b-param <level3bParam>
