4th isatty
Just encountered my first isatty annoyance.

Very dangerous what you're doing there. Once you're reading from a file, 4tH doesn't terminate the string anymore. You're relying on the zeros that were there when 4tH started.
The first behavior is explained because 4tH clears the input buffer from the vanilla stdin once it has read it. It would be annoying if a user typed in something, the program used the string partially and then the user was confronted with the trailing stuff left unread in the buffer.
In these cases, it is much better to use REFILL in connection with PARSE. Still, I wouldn't recommend it with binary data.. :-(
