This is an excellent question. One that I would resolve by the following:

Good so far but I would go ahead and assign $File:
FILE=${FILE:-1}

Still good...

I prefer to do things like this for a line by line read without affecting
the IFS env variable.
while read -r line
do
echo $line
done < $FILE
That will work fine. Now, if you want to go the route you were above by
affecting the IFS variable then you can set IFS like this:
IFS="\n"
for line in $(cat $FILE)
do
echo $FILE
done
Let me know what you end up choosing. BTW, I use ksh as my shell of choice
for scripting. If sh doesn't understand the above substitution for IFS try
ksh.
