Fix/truncate columns in stat command

[jackleland]

As submitted by Josh H:

nlds stat could be a bit clearer, the columns start to run into each other a bit (see picture). That also makes it a tiny bit harder to copy the id for any one transaction (I can't just double click on the number to select it, I have to manually click and drag to exactly the right point) - not a huge thing but a bit annoying.
