I think that something is seriously wrong with it, but... I don't know
how to fix that
When the command is "native" its executed, when the command is "simple"
this procedure tries to execute it, but when the command is "group" its
only passed through ocd_usage (and not executed probably). There is no
case of "unknown command" and failure of "group" type is always because
of "too few parameters".
"usage" for "group" always returns something - for known and unknown
commands the output is pointless as:
>> usage reset halt

I'd like to help, but I don't know how - I suppose that some deeper
knowledge of OpenOCD is required here.
