Have CommandObject::CheckRequirements() report the largest missing 

requirement for a command instead of the smallest.  e.g. if a command
requires a Target, Process, Thread, and Frame, and none of those
are available, report the largest -- Target -- as being missing
instead of the smallest -- Frame.
