One (semi-)realistic case I came up with, one shell sits in a
directory, someone else first moves the directory, then deletes it,
then the shell tries to 'cd ..'. In this case I would like it to end
up in the new parent directory as it does now [1], not the old
"$PWD:h". (with chasedots/-P) (and even if I did 'cd .' first for some
weird reason).
