Patch Set 2:

I spotted some weird behaviour:

  - Start up a test program,
  - 'tui enable'
  - 'layout next'
  - 'layout next'

At this point you should be in SRC/ASM/CMD layout with the ASM window focused, and its border coloured on just three sides, left, right, and bottom.

  - Scroll the view up (up arrow key), and the top border suddenly becomes coloured.

This seems a little odd!  Now,

  - 'focus prev'

You should still be in SRC/ASM/CMD layout, now with the source window focused, and its border coloured on all four sides.

  - Scroll up (press the up arrow key), you should see the bottom border loose its colour.

This seems odd.
