Right, I think that if there are any programs this change is likely to
break, it's programs that use stdio to read from a tty.  I could even
see an argument for giving stdin, specifically, non-sticky EOF when
connected to a terminal (kinda like how stdout is line-buffered when
connected to a terminal). But I would want some evidence that there
_are_ programs that would break without that, before we spend any time
coding it up.
