If a page has a discussion page, which is then removed, ikiwiki seems not
to notice that the discussion page has gone away, and does not update the
link to it in the action bar.

+Looks to me like loadindex is populating %destsources with information
+that the old discussion page exists, which isn't invalidated when ikiwiki
+discovers that the page is gone. This leaves dangling links whenever *any*
+page is deleted, not just a discussion page. --Ethan
+
+Here's a patch that trawls through %destsources deleting pages when they
+are found to be deleted. It's a little inelegant, but it's simple and it
+works. --Ethan
