* Has bugs updating things if the bestlink of a page changes due to adding/removing a page. For example, if Foo/Bar links to "Baz", which is Foo/Baz, and Foo/Bar/Baz gets added, it will update the links in Foo/Bar to point to it, but will forget to update the linkbacks in Foo/Baz. * And if Foo/Bar/Baz is then removed, it forgets to update Foo/Bar to link back to Foo/Baz. As of 1.33, this is still true. The buggy code is the %linkchanged calculation in refresh(), which doesn't detect that the link has changed in this case. Still true in 1.43 although the code is much different now..
