You should get 1 form any shell after this date unless you have an exit trap that would change this. Just tried more and found it's caused by having $(...) in my PS1. 93v- 2013-02-13 still has this problem.

Not a big problem but I think it better exit $?.
I tried the following and it did not exit 0.
$ ksh
$ false
^D
$ print $?
1

I tried the following on Scientific Linux SL release 5.5 x86_64 as well as
on an arm running Ubuntu 12.04 LTS with the same results:
$ ksh
$ print ${.sh.version}
Version JM 93u 2011-02-08
$ false
^D
$ print $?
0
$
Version JM 93u+ 2012-02-29 also returns 0 in this situation.

Or does that just mean that the behaviour is undefined? I am running ksh 93t+ 2010-03-05 and above sample as well returns 0 here in my Ubuntu/Linux 2.6 environment.
