Good point.  We might be able to compensate for this by trying
/bin/pwd, but only using the result if it exists successfully.  I know
that's not ideal, but I can't think of anything better.  If you have
any other suggestions, I'd love to hear them.

Try "ksh -x /tmp/doit".  The problem doesn't occur with sh, since it
doesn't set $PWD.
