Personally, I agree with Earnie.  I don't see any reason why pipes, etc
need to be text mode.  Anyway, at the moment, we're stuck with what comes
from Cygnus by default, which means pipes are text mode.  Assuming that
we will not get agreement on the subject of making pipes binary for good,
I think a switch would be the next best alternative (perhaps the current 
binmode switch could be used?)  However, currently with the source 
distributed with b19.x, pipes ARE text.  There is no facility for making 
them binary.  It is hard-coded.  I'll make a change to the bash source to 
check the binmode switch if nobody objects that this is bad pragmatically...
