It did, when I first wrote the patch, when the value for a required
option was not found; then I realized that error condition was already
taken care of in vshCommandCheckOpts() and I removed the check.

I agree that the vshControl argument can be removed. I'll get rid of it.

I'd rather keep it so that after the change all vshCommandOpt*() calls
are consistent. I don't see the harm in doing so, but maybe I'm missing
something?

Cheers.
