Yes, I *could* be mis-remembering things.  I've just tried and you're
quite right regarding use in the shell.  However if you look at
/usr/share/themes/Emacs/gtk-2.0-key/gtkrc it definitely does 'move to
end and then delete:-

  bind "<ctrl>u" {
     "move-cursor" (paragraph-ends, -1, 0) 
     "delete-from-cursor" (paragraph-ends, 1)
