The `IkiWiki::pagetitle` function does not respect title changes via `meta.title`. It really should, so that links rendered with `htmllink` get the proper title in the link text.

and a title is added. Nothing updates "A".
The added overhead of rebuilding every page that links to B when B is

That could be hundreds or thousands of pages, making interactive editing
way slow. This is probably the main reason I had not attempted this whole
thing myself. IMHO this calls for some kind of intellegent dependency
