Title: Small fix for final separator of status-left

I hacked lib.sh to make the last separator in status-left the right colour, depending on which segment was the last to output something.

`if [ -z "$output" ]; then continue`, wasn't working, so I wrapped the entire output in `if [ -n "$output" ]` instead.
