I like the idea (not sure if that's because I suggested it :-P) but, I have a
few comments. The patch doesn't touch iface-edit, which is not generated from
cmdEdit, though the right fix might turn out to be generating cmdIfaceEdit
together with cmdPoolEdit and cmdNetworkEdit.

And IMHO *edit commands are always interactive even when not called in virsh
interactive mode so I'd prefer this behaviour to be unconditional. I can't
imagine anyone sane to call virsh edit from a script, it's much easier to just
call virsh dumpxml, change the xml and virsh define it back.
