Good job it doesn't do that then - although be careful what "data
pending" means. If the buffer contains "wombat" and you are in ICANON
mode then there is no data pending, and poll() likewise will say there is
no data pending. Only when newline is hit do you have data pending (which
is why test t3 is buggy)
