The version of ksh shipped with AIX 3.1 is `11/16/88 NLS', which is basically
Korn's initial release + IBM internationalization stuff.  According to the
ksh changelog, posted to comp.unix.shell by Larry Cipriani, this bug was fixed
in ksh 11/16/88a to "agree with the man page".

There are quite a lot of ksh-88 fixes; it's now up to version 11/16/88e.  I
imagine IBM will eventually upgrade to a more recent base release.
