I'm running the 1.2 shell, and I've got a functioning pushd that looks like
it has the same ultimate source as the one in the KORN shell book.
I've forwarded it to Augustine Cano, maybe we'll get a followup report.

There's evidently a P D version of the Korn Shell posted recently;
I've seen some "bug reports" for it posted.  Sadly, I don't have it.
And I don't know how good it is.  But it's SOMETHING.
