This is a followup on a comment from me in T1604.
Right now tab completion is "ugly" on long named node names. e.g.
```
vyos@vyos# set interfaces wireless wlan0
Possible completions:
+ address Address for this interface
> bridge-group Interface bridge group
> capabilities HT and VHT capabilities for your card
channel Wireless radio channel
debug Enable hostapd logging to syslog
description Description for this interface
> dhcpv6-options
DHCPv6 options
disable-broadcast-ssid
Disable broadcast of SSID from access-point
disable-link-detect
Ignore link state changes on this interface
expunge-failing-stations
Disassociate stations based on excessive transmission failures.
> firewall Firewall options
hw-id Media Access Control (MAC) address
> ip IPv4 routing parameters
> ipv6 IPv6 routing parameters
isolate-stations
Isolate stations on the AP so they cannot see each other
mac Media Access Control (MAC) address
max-stations Maximum number of wireless radio stations
mgmt-frame-protection
Management Frame Protection (MFP) according to IEEE 802.11w
mode Wireless radio mode
physical-device
Wireless physical device
> policy Policy route options
redirect Incoming packet redirection destination
reduce-transmit-power
Transmission power reduction in dBm
> security Wireless security settings
ssid Wireless access-point service set identifier (SSID)
> traffic-policy
Traffic-policy for interface
type Wireless device type for this interface [REQUIRED]
+> vif Virtual Local Area Network (VLAN) ID
```
I'd expect a more eye-candied output like:
```
vyos@vyos# set interfaces wireless wlan0
Possible completions:

Keeping the 80 characters line break (for serial connections - yes I heavily
use them in 2019)
This is just a cosmetic change. I guess migrating the long names of nodes
requires unending effort
