As an example of what I mean look at what windmove-left does when
there is no window to the left. It then raises an error.

If debug-on-error is true I then get a chance to debug my behaviour. I
am not sure that makes sense.

The behaviour is different, but I think it should be similar to what
scroll-down/up does when it reaches the border. I think there should
be a unified behaviour. Making the visual bell default seems good, but
why not implement it as `command-level'?
