It may in places, but it turns out the 'value' formatter is most useful,
especially in the get_or_create_* functions where you really only need a
single value, avoids an eval or extra subshell.
group_id=$(
# Creates new group with --or-show
openstack --os-token=$OS_TOKEN --os-url=$os_url \
--os-identity-api-version=3 group create $1 \
--domain $2 --description "$desc" --or-show \
