Tricky stdin buffering problem.
An easier fix would have been:
hSetBuffering stdin NoBuffering
But that approach is less robust; even with NoBuffering, anything that
uses hLookAhead causes 1 byte of buffering. And, any reads from stdin
before hSetBuffering would still cause the problem. Instead, I used a
bigger hammer that will always work. It involves a bit more CPU work,
but this is data that is already being fed through ssh; copying it one
more time won't cause a measurable performance impact.
