Change rules size only on SIGWINCH. $COLUMNS isn't updated on SIGWINCH yet so "tput" is used. For better performance ruler is calculated by substring. Moving ruler handler to trap cleans console from garbage when "set -x" is set in interactive session. It is useful during debugging of bash completion.
