For backwards compability, the output does not change (even
though the label "current" no longer matches the spelling of
the option that would trigger that number in isolation), and
we accept "--current --live" as an undocumented synonym for
"--active --live" to avoid breaking any existing clients.

existing flag handling to expose VIR_DOMAIN_AFFECT_CURRENT support.

VIR_DOMAIN_VCPU_MAXIMUM : 0);
This line should have read "if (current)", not "if (active)".
