. Changes:

	- Don't show the big vertical line.

        - Add an arrow to the right before call instructions

        - Scrap bogus loop detection and instead start showing
          arrows from jump (fwd or back) instructions to its targets
          when cursor is on jump instruction. Press 'j' to toggle this.
