Using a completion helper in op mode like:
```
<completionHelp>
<path>vrf name</path>
</completionHelp>
```
will generate the following `node.def` file:
```
cat /opt/vyatta/share/vyatta-op/templates/show/vrf/node.tag/node.def
help: Show information on specific VRF instance
allowed: /bin/cli-shell-api listActiveNodes vrf name
run: ${vyos_op_scripts_dir}/show_vrf.py -e "$3"
```
The problem here is a call to `/bin/cli-shell-api listNodes vrf name` will return: `'bar' 'foo'` see the `'` quotes. The old `node.def` implementations got rid if the '' by using shell code like:
```
allowed:
local -a bnodes
local -a nnodes
eval "bnodes=($(cli-shell-api listActiveNodes protocols bgp))"
for b in "${bnodes[@]}"; do
eval "nnodes=($(cli-shell-api listActiveNodes protocols bgp $b neighbor))"
echo -n "${nnodes[@]}" ' '
done
```
Which removes the `'` quotes. Question - why is this of no issue in configuration mode?
