Be more conservative with aliment symbols

Previous code assumes model and adapter names were never longer then 20
characters.
Now this is 30 chart.
The lines are now around 40 char long, which still fit in most terminal,
And even it overflow in readably small terminal, Its still readable

We could loop over all names, to calculate the max length.
But this adds extra complexity, and only sometimes make the select menu look nice.
