unnumbered sections in pdf bookmarks

[Alexandre Duret-Lutz]

Hi people,

I have a Texinfo document using unnumbered subsections, and I am
viewing the pdf created from it with Acrobat reader.  In the
bookmark window these unnumbered subsection are displayed aside
from the section they belong to.

== snip == snip ===
\input texinfo   @c -*-texinfo-*-
@setfilename unnum.info
@titlepage
@end titlepage

@node Top
@contents
@node A
@chapter Numbered Chapter A
@node V
@section Numbered Section V
@node W
@unnumberedsec Numbered Section W
@node X
@unnumberedsec Numbered Section X
@node B
@chapter Numbered Chapter B
@node Y
@unnumberedsec Numbered Section Y
@node Z
@unnumberedsec Numbered Section Z
@bye
== snip == snip ===
compile with 
% texi2dvi --pdf unnum.texi

   from Acrobat I can see a bookmark layout like this
 
       > Numbered Section A
            Numbered Subsection V
         Unnumbered Subsection W
         Unnumbered Subsection X
         Numbered Section B
         Unnumbered Subsection Y
         Unnumbered Subsection Z

   althought it should be

       > Numbered Section A
            Numbered Subsection V
            Unnumbered Subsection W
            Unnumbered Subsection X
       > Numbered Section B
            Unnumbered Subsection Y
            Unnumbered Subsection Z

I don't speak TeX well enough to make a change in texinfo.tex,
but maybe someone already fixed that (if is possible) or has a 
work-around.
