sed will change text on a line-by-line basis. So, from the man page:

     Normally, sed cyclically copies a line of input, not including its termi-
     nating newline character, into a pattern space, (unless there is some-
     thing left after a `D' function), applies all of the commands with ad-
     dresses that select that pattern space, copies the pattern space to the
     standard output, appending a newline, and deletes the pattern space.



So, for what you want, you'll need some thing else. I'm going to suggest 'ed',
and leave the ed script as an exercise for another reader.
