If a page inlines some other page (such as this page by the bugs page),
and the page is removed (such as by this page being linked to bugs/done),
the inlining page is not updated to remove it.
+
+This only happens if the page is removed from the inlined globlist due to
+a tag changing; the problem is that once the tag is changed, ikiwiki does
+not know that the page used to match before.
+
+To fix, seems I would need to record the actual list of pages that are
+currently included on an inline page, and do a comparison to see if any
+have changed. At first I thought, why not just add them to the dependencies
+explicitly, but that fails because the dependencies globlist fails to match
+when a negated expression like "!tag(bugs/done)" is matched.
+
+So, quick fixes aside, what's the generic mechanism here that a plugin can
+use to let ikiwiki know that a page should be updated if some other page
+stops matching its dependencies globlist?
