Chris, I think this is ripe too, virsh may be a bit late but I would rather commit this before 0.8.3. ACK, For virsh there is always the possibility to do this from virsh shell where we have more control over how the input line get parsed. Maybe the solution is to make sure this works well from inside virsh shell and add a warning at the command help level indicating that using them from the shell invocation may lead to surprizes.
