6 years ago I'd say this particular issue is not with the conventions, but with the insufficient documentation for markup inside command blocks.
That said, I'd love to have some reference for the command block shenanigans, too - it's a rater murky topic. Even the official AsciiDoc(tor?) manual does not say enough.
{nbsp} in a command block does not render correctly unless the block is preceded by [subs="attributes"], as in the following example:
[options="nowrap" subs="+quotes,verbatim,attributes"]
ansible-playbook --private-key=/etc/pki/ovirt-engine/keys/engine_id_rsa -i /usr/share/ovirt-engine-metrics/bin/ovirt-engine-hosts-ansible-inventory --extra-vars "{nbsp}cluster_name=_ClusterName ovn_central=_OVN_CentralIP ovn_tunneling_interface=_VDSM_NetworkName" ovirt-provider-ovn-driver.yml
