ksh's cd tries to do too much

Ksh does some pre-parsing on the argument to 'cd'. It removes from the
argument all the '..' and the name before the '..' (for optimization, I
guess):
cd _not_a_directory/../_junk_/..
has no effect, even though 2 directories in the argument don't exist. The
problem is that if you type:
cd _valid_CDPATH_directory/..
it has no effect either and I think that's a bug.
$ echo $CDPATH
:/a/b/c
$ cd /a/b/c/d
$ pwd
/a/b/c/d
$ cd /
$ ls d
d: No such file or directory
$ cd d/..
$ pwd
/
This works with /bin/sh (the shell would put me in /a/b/c) and I didn't find
anything in the man page that would mention this as a 'feature'.
