If the next character on stream s is a newline, skips it, otherwise leaves the stream untouched. Returns :line-start, :stream-end, or :body to indicate the relative location of the next character on s. The stream must either be an instance of LineNumberingPushbackReader or duplicate its behavior of both supporting .unread and collapsing all of CR, LF, and CRLF to a single \newline.
