perhaps I could revisit that and make it do a pipe (we don't use pipes
in many places, and in case the logic is rather ugly ;-)

you mean something like

        ( command ) <input

I hadn't thought about that.  I've been burned with some shells that
won't work properly if I redirect to an arbitrary command, and use
'cat' if there's a question about it.  In either case, there's no
recovery if the command contains an unbalanced parenthesis...
