OK, I've reinstated that sentence but swapped versions to say:
 Note: code may not be copied from Qt into KDE Platform as Qt is LGPL 3 only which would prevent it being used under LGPL 2.1

I've updated it say to 'web server'.

I've added "or compatible licence".  All our current wikis are CC-BY-SA 3.0.

The previous requirement was the copyleft GNU FDL so there's no change
there.  I've added "or compatible licence". I've also added a note
"Note: CC-BY-SA 4.0 can be converted to LGPL 3."

It's just an option, same as before, I just changed CC 3 to CC4 which
allows for more compatibility with GPLv3 licenced works.  I've also
removed the requiment for the files to be "standalone" as with CC4
being compatible to GPL 3 they can be mixed with code if it's a GPL3
