We ought to think about the interaction between text (and bytestring) 
and the new Unicode IO library.  What does text have in the way of IO 

I've been wondering about what bytestring's hGetLine should do.  Right 
now I have it doing decoding and then taking the low 8 bits, but that's 
not right.  OTOH, looking for '\n' in a stream of bytes doesn't seem 
right.  Maybe it should just be deprecated.
