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

[Sebastian Urban]

Alright, back from Texinfo.

Thread link:
https://lists.gnu.org/archive/html/help-texinfo/2020-05/msg00031.html

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
>> bookmarks) has ``Some text'', while I was hoping for “Some text”
>> (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.
