[ksh93-integration-discuss] meaning of "obsolete second form of cd" in the ksh man page?

[Bernd Finger - Sun Germany]

Hi all,

I just installed ksh93 on my OpenSolaris systems, as a default shell for user 
root and my regular user. I'm quite impressed, and I hope this will be the 
default shell for Solaris soon!

In the man page, in the "Built-in Commands" section, under "cd", I found the 
following text:

--->
      cd [ -LP ] [ arg ]
      cd [ -LP ] old new
.
.
.
           The obsolete second form of cd substitutes  the  string
           new  for  the string old in the current directory name,
           PWD and tries to change to this new directory.
<---

What exactly does "obsolete" mean? I am using this feature from time to time, so 
it would be great if we can keep it for future releases.

I suggest removing the word "obsolete" from that paragraph in the man page.

Regards,

Bernd
