Tom Collins 2998647c4e py/lexer: Simplify lexer startup by using dummy bytes and next_char().
Now consistently uses the EOL processing ("\r" and "\r\n" convert to "\n")
and EOF processing (ensure "\n" before EOF) provided by next_char().

In particular the lexer can now correctly handle input that starts with CR.
