It'd be helpful to know about the use cases for such feature though.

My assumptions:

- This would only be useful in interactive sessions. Portable scripts would
not have access to this feature, and so in these cases the script writer
must explicitly consider the case where $PWD is unlinked while the process
is running. Or decide that it's not worth handling.

- In an interactive session: What are the conditions that lead to a
directory being removed without the user's knowledge?

- Also, what's wrong with letting a user deal with this by issuing `cd ..`?
Surely, this doesn't happen frequently enough that it merits increasing the
complexity of Bash to handle it automatically.
