There are susv4 web pages which you can download and pull up with  
"links" or similar if it really bothers you.

Trying to beat sane behavior out of bash is not a fruitful endeavor:

   cd
   mkdir missing
   cd missing
   rmdir ../missing
   pwd -P
   cd ..
   ls
   echo $PWD

I'm not copying that behavior.
