    sh: Implement the cd -e flag proposed for the next POSIX issue.
    
    This reflects failure to determine the pathname of the new directory in
    the exit status (1). Normally, cd returns successfully if it did
    chdir() and the call was successful.
    
    In POSIX, -e only has meaning with -P; because our -L is not entirely
    compliant and may fall back to -P mode, -e has some effect with -L as
    well.
