that's what happens. I could not find the relevatnt part in sources -
anybody (Geoff) - could you get a look:
This was for

for i in 1 2 3 4 5
do
 bla bla bla
done

Cut'n'pasted in another shell. As you see, after it gets first new line it
does ioctl(10, TCSETSW,...) before PS2, that, unfortunately, throughs away
all pending input :-( The following FIONREAD is useless in this case.
