correctly placed @part before @node can be in ignored Top node

[Patrice Dumas]

Hello,

@part is naturally placed before @node and therefore would be ignored
for the first node after the Top node.  Here is an example:

 @node Top
 @top top

 @part Part 0

 @node chapter node
 @chapter chapter

If, instead, the @part is between the @node and @chapter, the output is
correct in TeX, HTML, and DocBookbut this is not what is expected.

 @node Top
 @top top

 @node chapter node
 @part Part I
 @chapter chapter

 @bye

There is an error message:

./texi2any.pl part_node_chapter_appendix.texi 
part_node_chapter_appendix.texi:5: warning: @node precedes @part, but parts may 
not be associated with nodes


Any idea on how to improve on that?
