When I tested this I needed no "extra" \n in the reply footer.
All the initial \c does is to prevent *prepending* \r\n before the
footer text; this is obvious from the code.
The \c has no effect on appending the final \r\n. That decision is
made independently, also obvious from the code.
Now, the effect of \c *after* the beginning of the footer is
undefined. Don't do that.
Also undefined is the effect of \c with malformed responses, such
as responses with bare \n characters instead of \r\n.
