Okay, the patches look good to me. And I would merge them right away,
but there is a slight change in behaviour in virsh after your patch 2/3.
And you even describe it in the commit message:

Previously we had:

virsh # domstate<TAB><TAB>

just "--reason" was offered. Now, after the change "--domain" is offered
for completion too. This is important so that we know which completer
should we call for the following input for instance:

virsh # domstate --domain<TAB><TAB>

In this case we want to offer list of domains.

I'd really value output from others whether this might work or is this
change something we don't wanna do?
