Steps to Reproduce:
1. Change a user path in /etc/passwd to have ksh as login
   shell and change the user home dir to end in a /
2. Have a "/home/shared" directory
3. Login as the user
4. Try to execute "cd ../shared"

Expected result is to change to the directory

Result is a failure to change the directory due to ksh
incorrectly parsing the relative path.

  Sample results testing my user after changing to have
ksh as login shell and adding a trailing slash to the
home directory:

$ sudo su - pcpa
$ pwd
/home/pcpa/
$ cd ../t
-ksh: cd: /home/pcpa/t: [No such file or directory]

  The attached path corrects the problem, but it may
be a better idea to prevent the slash being added to
the current directory (e.g. shp->pwd).
