The output from
```
show system uptime
```
is very hard to parse as it doesn't space between weeks/days/hours/minutes/seconds:
```
tim@ferrari:~$ show system uptime
Uptime: 2w4d22h54m9s
```
It would be much nicer to have a space between all the units (I assume month and year are also part of it)
Example Output with "fix":
```
tim@ferrari:~$ show system uptime
Uptime: 2w 4d 22h 54m 9s
```
