+       * tp/Texinfo/Parser.pm (_text_to_lines): Do not return an array 
+       containing a single empty string if the input is an empty 
+       string; instead, return a completely empty array.  This means
+       that parse_texi_line does not get as far into parsing for an
+       empty input.

        * tp/Texinfo/Parser.pm <root commands>: Do not associate a @part 
        command with a following sectioning command if another @part 
        command appears first.  This means there is no special support
