The code for TYI checks to see if the stream has a
rubout-handler to decide whether or not to echo the character.
I presume this is to avoid echoing the character when TYI'ing \n from a file. This screws streams which don't have a rubout handler
but want TYI to echo. Perhaps there should be some way to ask a
stream whether or not it is talking to a terminal. This would be
useful in user programs which want to make some sort of distinction
like this as well.
