xmlAddPrevSibling and xmlAddNextSibling had reverse semantics from those Sun Nov 12 12:12:22 2000 George Lebl <jirka@5z.com> * tree.c: xmlAddPrevSibling and xmlAddNextSibling had reverse semantics from those documented. And the only use on gnome-cvs I could find was bonobo-ui which used the documented semantics apparently. Thus I switched the bodies of these two functions.
