Actually, as I think about it, with STDIN I think pos doesn't matter.
(For seekable streams it does, since pos has to be left at the point
where the scanf match stops succeeding.)  So I think I can do a rescue
and set my pos-based variable to a dummy value.  Or maybe I should
just do that if it's a TTY.
