IMO completing numeric IDs doesn't make much sense, they aren't
descriptive at all and I don't really see a point for users using them
on a commandline. If you are expanding both names and IDs then you'll
have twice as much completion suggestions on an empty string.
Is there a case where it would actually make sense? Specifically in
virsh we almost always accept id/name/UUID interchangably for a
'domain'.
As I'm saying in the commit message - virt-viewer accepts --id, I don't
expect ID completer to ever be implemented for virsh because as you say,
domnames and/or uuids are accepted universally.
But adapting virt-viewer's completer is not going to be trivial anyway,
so we might as well drop this :-)
