This may only be true for Ksh93.  The Ksh88 man page says that
the exit status is 128+signum.  The Public domain Korn shell, and
ksh on IRIX 6.5, Solaris 7, 9, and 10 all exit with the standard
behavior of 128+signum.  So, it may be appropriate to change the
commit message and comment in t0005 to reflect this fact.
