Of course, .* is not a newline, unless that is all that is in the buffer.

\n is a newline in the regex

'\
' is a newline in the s result

N embeds a newline before the next line in the buffer. My example was:
  1. N puts a second line in the buffer, and as the buffer contains \n, it is printed.
  2. .* matches newline and all else when I replace the buffer with two constant lines using the '\' + newline.
  3. That prints too, as it also matches /\n/.
  4. You can pick up just the newline and lay it down 4 times using &.
