Subject: Powerpoint writer: Ignore links and (end)notes in speaker notes.
MS PowerPoint does not offer a way to insert links into speaker notes
text, so we match that behavior, and make our lives easier.
As for (end)notes, there is no clear solution to the question of wat
that would *mean*. The default behavior would be to add it to the
endnote slide, but that would put speaker note content into the public
presentation. The best solution would be to put the content at the
bottom of the notes page, but that would take some doing, and can be
added to the speaker notes feature later.
