Actually, MiNT stands for "MiNT is not TOS". Not MiNU.

The kernel sets the default UNIXMODE to "/brUs", so by default the
kernel is setting up the environment. So the user actually has to ask
for it to behave like TOS. So it's the other way around to your liking.

It seems binary mode is on by default unless UNIXMODE is set to "/rUs"
from a previous long ago commit from Frank in 2000.

I think I'm going to enforce scriptability now too, which I don't think
is any significant problem given that I think most people would want the
script that starts with #! to be interpreted as a shell script.
