You are right. I never noticed that vi put a newline in the
file, even if I put only a single character in. Yuck, I thought
vi wouldn't to that! In fact, it took some doing to get the
single char in there:

echo 'a' > t; ls -l t
-rw-r--r--  1 jfreeze  sm  2 Nov 20 11:40 t
printf 'a' > t; ls -l t
-rw-r--r--  1 jfreeze  sm  1 Nov 20 11:41 t


Thanks
