I think when point enters a partially visible line, redisplay should 
behave as if that line were invisible, i.e. scroll the display (by 
default, by half the window height) to bring the point's line into the 
visible area.  If such a change in behavior is not something that 
requires to rewrite large parts of the display code, I'd suggest to make 
it so.
