Make selection render like visual mode in vim

Browse Source 
Note that this causes trailing whitespace if you copy out of the pane with
the mouse.  This is the same as how vim renders this though.  nano takes a
different approach which doesn't result in trailing whitespace, but I find it
more difficult to see whether the ends of lines are highlighted.

If later I want the nano behaviour, remove the `+ 1`s in this patch.
