[libvirt] virsh help keywords vs. command prefixes

Hi all. I wonder if it may be more intuitive for the new help keywords to match the virsh command prefixes where they exist. For example "help nwfilter" would tell me about nwfilter- commands. Some keywords follow the prefix convention (nodedev, secret, snapshot, pool) but some do not (interface vs. iface-, filter vs nwfilter-, network vs. net-, volume vs. vol-). Minor observation and close to release but I thought I would send on feedback to see what people thought. Paul
