Oh, no!  What can we do?  I'm pretty sure I stopped using 2>/dev/null
at some point, and for a reason.

I think the problem was that ksh on AIX barfs when encountering
2>/dev/null on a shell builtin.  Ah, yes, here's the log entry:

/----

| Don't use "set +o history 1>/dev/null 2>/dev/null".  AIX chokes on

\----

Isn't that nice?  So.  Can we be sure that `ls' is never a shell
builtin, and that doing "2>/dev/null" on those commands never fails?
I think we cannot be sure.  (And also, the exit status of `cd' is
sometimes queried, and that's always a shell builtin.)

Does anybody have a suggestion?
