title: Does the C-m key combination in emacs generate "\r\n" or just "\n"
body: <p>The emacs docs for C-m key (ie. C-h k C-m) displays the following</p>
  
  <pre><code>newline is an interactive compiled Lisp function in `simple.el'.
  
  (newline &amp;optional ARG)
  
  Insert a newline, and move to left margin of the new line if it's blank.
  If `use-hard-newlines' is non-nil, the newline is marked with the
  text-property `hard'.
  With ARG, insert that many newlines.
  Call `auto-fill-function' if the current column number is greater
  than the value of `fill-column' and ARG is nil.
  </code></pre>
  
  <p>But it does not say <strong>newline</strong> is in the context of dos ("\r\n") or unix ("\n").</p>
