Re: [libvirt] [RFC] virCommandRun return error number

Not necessary. virCommand is DESIGNED for streamlined usage, so that it is much easier to read how the command is constructed without being distracted by error checking in the caller every step of the way. As a virCommandPtr has no semantic impact until it is run, it is sufficient to delay error checking until the caller is actually ready to run the command. Therefore, we wrote virCommandRun() to specifically check for NULL, and report an error at that time, so that the caller need not worry about virCommandNew* returning NULL. No bug here.
