You can give line addresses in sed like in ed or vi. Something
like sed -e '$! s/.*/\'&/g' should work, though the op might have
to experiment with escaping the single quote he wants to add.
Putting the expresion into a sed script file worked for me.
The $ address operator finds the last line the ! negates this address,
so sed will parse all the lines but the last.
