The outer loop of the parser was detecting end of line variations
'\n', '\r\n', and '\r' and checks for following characters. If
characters are discovered an exception is raised. If no characters
are following, the inner parsing code is passed '\0' to indicate end
of line.
Since there was no way for the inner code to ever receive a '\n' as
data, I changed the '\0' special value to '\n'.
