Ok, I am not sure either. I took Miles idea (as I understand it) instead 
and made this a globalized minor mode.

I have attached the original code + David's code in one file for 
convenience.

I added new functions for <home> and <end> keys. Those functions also 
contains a proposal I made long ago, but which was never installed then.

David, there is also a small change to end-of-visual-line. Can you check 
it, please? I do not understand your comment in that function.
