shells/ksh93 segfaults on suspend

[Greg Rivers]

The version of ksh93 currently in ports suffers from a bug that causes it 
to segfault on suspend:

$ pkg_info -I ksh\*
ksh93-20110208_1    Official AT&T release of KornShell 93
$ su -
Password:
# echo $KSH_VERSION
Version JM 93u 2011-02-08
# ps -p $$
   PID  TT  STAT      TIME COMMAND
60190   4  S      0:00.01 -su (ksh)
# suspend
$ jobs
$ dmesg | tail -1
pid 60190 (ksh), uid 0: exited on signal 11 (core dumped)
$

A bit of searching turned up that this is a known bug[1] that was fixed by 
Red Hat last April.  I don't know if they pushed their fix upstream. 
Should I file a PR for this, or are there plans to update the ksh93 port 
soon anyway?
