ksh bug fix update

Updated ksh packages that address various bugs are now available.

The ksh shell is a command interpreter intended for both interactive and
shell script use. Ksh's command language is a superset of the sh shell
language. The pdksh package contains PD-ksh, a clone of the Korn shell (ksh).

Previous versions of the ksh shell could enter an endless loop when a
particular directory layout was used. This update provides corrections to
avoid that problem.

Previous versions of the ksh package replaced the pdksh package. This issue
has been fixed in this update, but pdksh and ksh cannot be installed at the
same time.

Users of ksh should upgrade to these updated packages, which resolve these
issues.

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
