We shouldn't append a wiki link fragment onto a redlink; the edit UI is different from a page view, so appending a page-content fragment will at best do nothing and a worst conflict with the UI and scroll us down unexpectedly.
!! input
[[Zigzagzogzagzig#zug]]
!! result
-<p><a href="/index.php?title=Zigzagzogzagzig&action=edit&redlink=1#zug" class="new" title="Zigzagzogzagzig (not yet written)">Zigzagzogzagzig#zug</a>
+<p><a href="/index.php?title=Zigzagzogzagzig&action=edit&redlink=1" class="new" title="Zigzagzogzagzig (not yet written)">Zigzagzogzagzig#zug</a>
