Here is Dave Korn's bug fix:

| From: research!ulysses!dgk at research.att.com
| Subject: Re: ksh problems
| 
| I thought that I had fixed this.  The fix is to change line 768 of
| sh/builtin.c from
| 			if((a1=strchr(a1,'?')) && tty_check(fd))
| to
| 			if(a1 && (a1=strchr(a1,'?')) && tty_check(fd))

I also found the problem in the man page. There is a spot where it says

	.if \X=0 .IR rsh .
	.if \X=1 .IR rksh .

Both of these should be \nX.  I have found a few typos in the man page
and may post full diffs later, that is not as critical though.

Again, my hat's off (figuratively) to Dave Korn for his work and his help.
