> The following changes were made to that:
> * As it was observed in other submodule subcommand's ported function
>   that the number of params increased a lot, the variables quiet and
>   recursive, were replaced in the cb_foreach struct with a single

> * To accomodate the possiblity of a direct call to the functions
>   runcommand_in_submodule(), callback function
>   runcommand_in_submodule_cb() was introduced.
