That last bit's going to depend on what error handling happens when "cd
." fails, both internally and in the shell code.  Internally, the right
thing to do, presumably, is if we don't do the bogus PWD=. just leave
PWD as it was before, which seems natural enough.  Otherwise, as far as
I can it's the same basic case as before --- if it used to do some
sensible it still should.
