bug#41117: "Cut and paste" section name in bookmarks (PDF, Emacs manual)

Alright, back from Texinfo.

Here is the important part:

 >> 1.  In my "test" texi file there is a line:
 >>    @chapter ``Some text'' and the rest of the @TeX{} text
 >>
 >> The point is, when I export file to PDF (texi2pdf --tidy test.texi,
 >> with @documentencoding UTF-8), the bookmark that is created (PDF

 >> (curved quotes).
 >>
 >> I can "fix" it like this:

So... can't we have one exception?  As I wrote, it's in @section, so
it could be special case - one special case.
