Well, I thought on changing it at every buffer visit. But then I was 
thinking of user actions of course.

If the user visit a new buffer in a window, yes. My thoughts are not 
very clear, but seems like this could be done after each user command. 
Set the current directory to default-directory then. Would that not be 
clear enough?

Maybe it is not sane, but I think it is close to the logic used in 
cmd.exe on w32 so it will be no surprise to the user IMHO.
