        ^^^^^^^-- leave out, since this would now be printing ['<1st line>, '<2nd line>', '<etc...>']

                print "--------: ", i.rstrip() #(a) strip trailing whitespace, so print doesn't double it
                print "--------: ", i          #(b) splitlines above does the job

I forgot splitlines, so I was going to suggest (a) until I read your suggestion,
which I would then suggest using as in (b).
